I drove my 2016 Denali for 2 weeks when it went into limp mode. No matter how long I drove on the shoulder of the freeway, at a dangerous 35 mph, it would not regenerate. I finally took it to the dealer and they did a manual regen. I said, never again. At 1k miles, I took it to the performance shop and upgraded the exhaust, removed the DPF and DEF system, added a lift pump, did the CP3 conversion, removed the EGR, upgraded to 64 mm turbo (4" downpipe) and got an engine and transmission tune using the EZ Lync. The power and drivability is amazing and even with 37x 13.5 Toyo's, (which I can chirp in 2nd, 3rd and 4th gear) I get 22 MPG at 70 mph. Not bad for a 10, 000 lb 4x4 with a 10k rear winch and a 50g aux fuel tank

EZ Lynk is pretty sweet too. Nice to be able to monitor, clear codes, data log, and tune from the cloud. Been running that setup for 6 months now and it's been fantastic.

I have a weight reduced 15 lml that just rolled 160k. This was SUPER helpful! Thank you for taking the time to explain everything!

Can u do this same video but LMM duramax??

[nahrens]

Probably wouldn't hurt to look into an alternate firing order cam to get the stress off of front of the crank.

I got a question for you i got a 2011 lml durmax and i have a tuner on it when i bought the truck it was set for tow on the tunes well i was wondering does running it on street or preformace tune hurt anything?

I just sold my LBZ at 291k and bought a 2016 Denali LML with 53k on it. What is the best or healthiest tuning for it? I had EFILIVE from duramaxtuner on the LBZ but they don’t do that anymore.

Why in the hell would you replace a cp3 with the cp4?

Anyone have any experience with the Mishimoto intercooler? I grenaded my last turbo and trashed the oem cooler…. I only see mishimoto and banks high dollar coolers that are beyond oem. Or oem+ level.
I believe I may have overspent the bearing due to boost leak off a cracked oem intercooler. So. Thousands of dollars later I’m here.. any info is appreciated
