last summer i let one of my customers borrow my truck(6.0 03 silvy) that i tuned and he loved it. so he asked me to tune his 08 5.3. so i did the usual. pe timing torque management but now i am ready to punch this truck. from a dig it yanks all the timing out an acts like it wants to hold 250 lb/ft(logged delivered). and the pe feels like its at a fixed tps. i have little pe delay but this thing is a dog when you flirt with the thin pedal. here is a tune and a log. pretty much the default cfg with deliverd torque and gear. thanks rob it's not letting me up load the tune.

 

i think the tune file may be exceeding the limit which just goes to figure . i am about to eat the $100 worth of credits. a link to the hp thread. thanks again.
