[QUOTE="JD3020, post: 770779, member: 373"] I tweaked it some and got it pretty good, till i installed a Swamps IDM last night. Now for the first time ever its dropping cylinders when cruising at very light throttle, so time to tweak it some more. But i must say i'm pleased with the results. And something i noticed tonight, which i'm not sure if its been going on this entire time or what, but the truck isn't building more than 2300psi. DC is maxing out around 35%. The tune is calling for 3200psi. I'm assuming its a PCM/tuning related issue and not something mechanical. So do i need to start messing with the ICP DC table now? I have yet to make a single change to it. [/QUOTE]
