ok I guess I will start with the known upgrades on the truck.. it basically has a full ATR kit on it so pittbull chip, turbo, 3 "down pipe (straight piped), 7th injector, intake with cone filter, intercooler pump with second cooler and a built trans. and so here's what is going on, when the truck is cold it runs lie a scalded dog but when it gets warm or close to OT with a 160 t-stat it starts to break up over about 10 psi of boost and if you keep it hammered it will cough and spit and hardly accelerate it almost sounds like a jake brake on a semi truck. and at idle when it is hot it will puff about once every second. I have been fighting this for 2 years and any help would be appreciated greatly!
