for some reason it seems like my tourqe management gets turned back on or something some how. when i turn it off the install the tune, it does fine, leaves off the line like a champ. but after driving for a while and going through town and stuff, if i try to take off the line again it lags really bad, like as if im just letting off the break and rolling off the line with engine idle. maybe a little faster but not much if any. does anyone kno what the heck is going on? i restored my truck back to stock and it took off the line nice and good? wtf? and restored my diablo and re installed it and again, good for a little while, then its like it gets turned back on, someone help!

that's because every time you flash it, learned items in the pcm, such as your fuel trims, get reset...
and after some miles/time, things are relearned by the pcm and settle back in based on driving habits...
have you gotten your fueling dialed in so that your average LTFT's are in the 0 to -2 range?
doing so will give you better throttle response, better acceleration, stronger pull, and better mileage...
here's info on how to do it:
and for even better performance, you could get a custom tune written for your predator/truck by a diablosport CMR tuner...06MonteSS

after you highlight "off" in each one, you'd press the center button on the predator to enter/save the change...
then when done, press the ESC button a few times to back out of the adjustments, and it will ask you "Install tune now?" - answer/select YES, and it will install the modified tune to your truck...
and then the TM will be off immediately...
