OK so I got a 14 lml in the shop for cp4 leaking causing crank/no start. replaced pump(no metal shavings was found), after replacement I primed the fuel system got all the air out, cranked and the truck started but sounded weird and shut off. thought maybe air trapped but primed again and...

So I was planning on upgrading to a CP3 from the cp4 but come to find out Danville went out of business so I am stuck with the cp4 tuning. I know one place but I do not want a single tune I want to keep my DSP5 switch is there anyone out there that does the OG tuning for the LML trucks? IE non...

Looking for some advice. I’m about to replace the head gaskets on a ‘15 Sierra LML with 260,000 miles on it. It’s been deleted and tuned by previous owner. Other than ARP head bolts, glow plugs, water pump, and hoses, what else should I have replaced/upgraded. Considering replacing CP4 pump and...

I have a 2016 LML chevy that I rebuilt the stock turbo at 180,000 due to high carbon buildup. the unison ring was frozen and the truck made a squeal while starting and driving. no codes where thrown but I could tell the vanes weren't operating as they should. pulled the turbo and cleaned it up...

customer brought me the truck and the parts to rebuild the trans. said it needed a rebuild, declined a diag. (should have done it anyway but I didn't) stated it was slipping and would kick into neutral occasionally while driving. he later said it started all this after he hit a big root when...

Been reading some forms and was seeing that these codes would sometimes be thrown if the temperature outside became cold. Live in California and hardly drops below 25 degrees. Had a buddy give me free fuel about a year ago and the p140a code came up but after putting in regular fuel it went...

Howdy folks, longtime lurker, first time poster. Thought some of y’all would appreciate this. As an owner of an lml I heard about the dreaded cp4 failure early on and never quite felt at ease driving around despite all the recommendations to prolong life via additives etc… Finally bit the bullet...

I’ll preface this by saying I know there’s already threads about this but they’re not quite the same scenario. I’m desperate to fix this issue so here goes. I have a 2015 Duramax with 440,000 miles. Not a typo, 440k. Around 200k the truck was deleted and tuned and a FASS added. I had zero...

It's a stock 2016 with 225k. So I'm driving home today after work and getting the kids from school. I'm in medium traffic and go to accelerate and the truck has absolutely no power to accelerate.

Looking for some confirmation on what I suspect is my problem and recommendations. I have a 2012 2500hd LML 185,000 miles. The truck recently started staying in regen much longer than normal and now has gone into regen and hasn't come out for the last 450+ miles. Around 270 miles ago it...

Had a boost solenoid code ordered a kit with that and turbo vane sensor. Replaced everything was fine. Turbo sounds different when spoiling. When first start up and goes into high idle it kicks off for a second or two and back to high idle. When it kicks off the engine reduce power comes on then...

2016 lml. 221,000 miles(7100 hrs) deleted with a mild tow tune less than a year ago. This issue has happened 2 times in the past couple of weeks(otherwise running fine). I let the truck idle for about 10 minutes and let it get up to 160. Then I drove it for a few minute then after it was at...

Thanks to those of you who didn’t roll your eyes and move on after reading the title. I understand this is a fairly common issue and that there are a ton of threads on here regarding this issue. However, I still can’t figure this out. I most recently replaced the cv axle which was clearly toast...

I just installed my dsp5 switch and had issues with a check engine light due to (P0183) fuel temp sensor circuit a high) and wanted to know what it could be because a doubt that the switch would just cause that normally, I used both fuel temp pins in the 3rd ecm harness closest to the firewall...
