Product Description

CP3 Conversion Kit w/ Pump (Tuning Required)

S&S Diesel Motorsport, the world leader in common-rail diesel injection has developed a solution for CP4.2 high-pressure pump failures that have plagued the LML Duramax engine. The S&S solution is to remove the problem before it becomes a problem, by replacing the CP4.2 with a tried and true, bulletproof CP3 high pressure fuel pump.

CP4 high pressure pumps are the Achilles heel of the LML Duramax engine because of high failure rates, and commonly taking out the entire, very costly, high-pressure system with it (injectors, rails, lines). 

AVAILABLE OPTIONS:

  • LML CP3 conversion kit w/pump – Competition Use Only – Tuning Required

Great product, had everything I needed. Installation went great, got it all done myself in my garage in about 6 hours. Truck runs awesome with engine and trans tunes.

Andy

Kosevich

yes working good so far

Steve

Noriega

Very happy with my order. Could have used some instructions on the install. Thanks Youtube. Also don't really understand the trans tune. Didn't get any verification it was installed on the tuner or even how it is installed. Don't even know if I really have it.

Tracy

Funderb

Yes 😊

Darrell

The kit works great. The DPF and DEF deletion pipes fit perfectly. The EGR Kit had everything I needed and the RaceME Ultra was easy to install. The way the truck runs now is awesome, The horsepower and fuel mileage was exactly what I was looking for. The fuel mileage on my 2017 Dodge with the 6.7 cummins with from 15-16 MPG to 24-26 MPG on the highway and from 11-12 to 18-19 in town. I'm extremely happy with my purchase. Thank you.

Dave

Great product will be ordering more very soon!

Jaron

Exactly as described. I love it my miles per gallon on the highway or approximately 25 miles per gallon now at 78 miles an hour on cruise on level ground. Very happy. Not to mention all the extra horses

Everything I have ordered so far has installed and functioned without fail. Shipping has been prompt. Customer service has been knowledgeable. I would recommend these products.

Installation for exhaust was pretty straightforward. Internet connection is slow where I live, so download of the tune was pretty time consuming. Also had to take off my dashboard to access unlock location for ECU. On the upside, easily added 3mpg - sometimes a little better when taking it easy. Amazing to get almost 30mpg (sometimes low 30's) out of a 1/2 ton pickup truck.

Jeffrey

Burns

Hello, your kit worked awesome. No issues at all. Truck runs great. Thank you

EGR kid was a breeze, for me at least. Everything I needed was in the kit. Only thing I want to say to help for future kits, is that the gasket for the intake neck/tube, it was bent and on the verge of tearing. I was able to reuse the original one on my truck since it is a very low mileage truck. Otherwise, thank you and hope I can find something on your website I can use!

Anthony

Bran

Install went awesome, instructions were good and everything went smoother than expected. Thank you.

Hey guys just a shout to you all! Thanks for supplying us with another great kit. Everything went together perfectly and the tuning is awesome! Thank you for another great experience!

The truck is running pretty good now thanks to your tunes and email help. I ran the 60hp tune for a few days then loaded the 100hp. Ran a tranny learn session out on the interstate immediately after the flash. Truck runs better on the 100hp than the 60hp tune in my opinion. No rolling coal, just a little "coal dust" when accelerating. The mileage is fantastic compared to what it was getting before the turbo replacement and tuning. It was 13-14 mpg before the swap. Now running the 100hp tune, I'm getting 21-22mpg. Unbelievable! On a fresh refuel, I reset the mpg display on the truck. The first 125 miles saw 22.5 mpg! After five days of mixed driving, it was still holding 21.8 mpg. Now, the big question is: How accurate or valid is the PCM calculation and display? Who care? Before it was reading 13-14 m mpg. Now it's showing 21.8 mpg. That makes me happy and that a good thing. I will run a manual calculation when I refuel again in a few days to cross check. Thanks again for your help and patience.

Awesome company, great products/tunes!! Very fast customer service!

Brock

Everything worked out perfectly. Super happy.

Rian

Mckinnon

Product was not really compatible with the C/C as turbo is smaller so GDP will only give me 1 tune. I understand why but, I bought the 5 position switch was so I could adjust power as at times I do not tow and others 30k lbs. Other than that like the tune and GDP tech line was very, very helpful So can't use the 5 position switch but will keep until I install a larger turbo as per GDP. Thanks for the product and it really sounds like a truck now.

Did exactly what I wanted.... And would definitely recommend

Jesse

5 stars Fast shipping, quick response to my email, excellent products. Tune loaded quickly with no issues and shifting is smooth with the tow tune but I'm still experimenting. I needed a exhaust that wasn't to noisy and yours a worked perfectly and no leaks from the clamps. I did remove the 4 inches from section of straight pipe to fit my long bed crew cab but that seems to be the norm so the same pipe will fit the long bed mega cab. You were a word of mouth recommendation and I'm glad I remembered the name of your company. Thank you for helping me bring my truck back to life.

Kenneth

Polley

Yes very happy with all your service. Thanks

Wayne

John, I'm a big thumbs up on your team overall. Very pleased with the level of support prior to, during, and after the changes I made. The number one differentiator between your team and others is the ability to pretty quickly get a live person on the phone and if needed for them to remote into the laptop connected to the vehicle. There were a few issues, but quickly addressed and or your guys confirmed for me what was happening and that all was well and as expected. Good work by all! A+ so far! Thanks Chris

Brent

Kramer

I am stoked! Thank you ALL for being a part of the solution. It burns me up to know the amount of great engines out there being ruined by the ridiculous laws and science being forced on great Diesel engines. No doubt about it, there are less than a handful of un-needed factories blowing more pollution into the world than ALL of the diesel engines combined. Thank you again for all you do! God speed.

Mike

Thompson

I would just like to say thank you for such a great system your team sold me. I had everything I needed and made this kit installation go very smoothly. I was very nervous going into this, my boys kept telling me it will be fine. The Agent 3 device was such an easy install it was crazy. Everything connected very easily and meshed well with my Banks equipment I added with it. When I have heard folks say it will wake up your truck, I had no idea until I started driving it. Completely different truck. Thank you for supporting this equipment and making this high value upgrade a smooth one. I definitely am spreading your name out there.

Gary

Morrison

10/10. I had a little mishap with the EGR kit getting shipped but after a late-night email, that was responded to extremely quickly. Customer service top notch. Install quickly and easily. It is a great product and a great company.

Great!!!

I'm really happy with the Ecodiesel delete kit, which comes with an ECM and transmission tune.,My first impressions are really positive.,I installed this kit last weekend and the results have been outstanding in terms of power and fuel efficiency.,My 2016 3.0L Ecodiesel was in bad shape, stuck in 'limp mode' due to an electronic throttle fault and a DPF that was completely full.,The dealer wanted to charge me over $3,000 to replace the DPF filter, but I decided to do the installation myself.,While it was a tough process, it was definitely worth the effort.,After completing the hardware installation, I cleared the engine codes and downloaded the ECM/transmission tunes.,I went for the 40hp tune, and I can really feel the difference - there's better throttle response and a 2mpg improvement on rural roads so far.,We'll have to wait and see about the long-term durability, but I'll definitely update if I run into any issues.,Overall, I'm really pleased with the product, the instructions, and the customer support.

Everything I needed was in the kit I was very happy with Everything except the shift on the fly selector. I spent 2 hours installing it in a very inconspicuous location. After I installed it we could not get the proper voltage reading for it to work correctly with my truck. So now I have it still mounted in my truck but I had to unhook it so it was a $150 item that I won't be able to use. But everything else worked very well and I am pleased with the outcome of the installation. Thank you for your products. Will be purchasing more form your company in the future

The kit was just what I needed. The only thing is there one of the hose connections that is plastic and should be metal. I swaped it out with a metal one and all is good. Thanks for shipping the kit quickly.

Chad

Loker

Ordering process was great and everything arrived quickly and intact. The GDP tunes seem decent although there is some smoke on level 1 where I wouldn't think there would be any. Overall very satisfied with the product.

C

Gilliam

I am more than happy with it. I have completed the DPF removal and straight pipen install. I have not removed the EGR. I can say that I have picked up more power and 3 more mpg towing. I have an 8k pound bumer pull camper. There is a little black smoke when I punch it; none if I drive "normal". My wife said it is louder, who asked her. I have been on the fence but your price and the extra $100 off, with free shipping was the factor. Thanks for the entire process from ordering to installation videos.

Scott

Awesome fast shipping

Mike

The product worked perfectly, solved all my problems. Thank you.

Michael

Packages arrived and in good shape. When I had any questions someone would follow up with an answer. My RaceMe Ultra was easy to install and had no problem with the EGR delete kit. I did have a problem with my pipes due to the bend in the pipe that replaces the muffler. Only 2 ways I could put it. The bend up or down would not let me hook up my hanger mounts for support.

Geoffrey

Truck runs like a scalded dog! Had issue with muffler not being sent with original order and had to switch to EZ link tuner. Other than than N that, very pleased

Well let's just start this out by saying I have a 16 ram 6.7 and I ordered the ezlynk with the LION package shipping was very fast and everything was complete I deleted my rig it took a complete weekend because we had a little hiccup with the ezlynk not hooked to a technician but as soon as GDP opened the problem was completely fixed the five position switch was perfect and everything functions great the tip for the 5in exhaust is completely over the top but as a dump would look great I'm very pleased with the tunes just took my camper on a 80 mile journey and have ZERO complaints now the truck is a beast I highly suggest you go with DIESEL LION for the simple fact that it was very easy to install and use ...... on a side not I do also recommend headstuds!!!! Definitely worth it THANK YOU DIESELLION.COM for everything I will be sending business your way with all my friends

good tunner worked the way they said.

Bat

Exhaust came in on Tuesday. Well packaged and perfect box. Got the truck completely done today. Slow day at the shop so I got it all done. I want expecting that much power honestly. What a difference. Already 3.5mpg better. Truck is a monster now. Shocked really. Sounds sick too!!!! Thank you guys for the product, communication. Perfect. It's like a new truck.
