My biggest challenge tuning this combo was transient fueling no doubt. There was some minor clearance issues with the factory a/c bracket I used injectors from an 01 6.0 lq4. The setup with the stock top end put down 259hp@ 4900rpm / avg 310 torque from 1900-4000. That was through an nv3500.
I never completed the cpc swap just built some brackets to mount the coils. Still running stock type distributor setup. Just using a marine type at the current time. Never got a chance to dyno the truck after the cam swap and milling the heads. If I were to guess ide say its probably putting down just over 300 to the tire. Through the 4l80 & Fti 3800 9.5" converter. Im curious what injectors your using?
