TW 6 POS chip issues...Touchy throttle
I have been trying to figure out my touchy throttle issue since I bought my chip in Aug of 2012. I have sent it back 2x for a reburn with no luck. I dont know if it is my truck or the chip. Im starting to think its my truck thats causing the problem.
When I accelerate from a stop on any position other than stock the truck takes off abruptly. It will spin the tires on anything but dry pavement. It just snaps your neck and takes off. It doesnt really shift all that great either (stock is better) and when the torque converter locks it bogs the truck down. Needless to say I just drive the truck in the stock position. I used my AE and watched my ICP and when it takes off abruptly the pressure jumps accordingly. (700 to 1500psi instantly)
I just bought a different PCM thinking the connection was bad where the chip contacted it, no change. So I thought my IPR was sticking, just replaced that with a new motorcraft one, no change. My ICP sensor is fairly new also. And my CPS is a year old gray one. Both front ABS sensors are brand new and I cleaned the rear one on the diff. The only thing else I can think of is my TPS giving off a bad reading.
Does anyone have any ideas what else it could be? Im getting sick of throwing money at my truck for no reason.
BTW when I take the chip out or drive in the stock setting I have no issues at all. Throttle is smooth and my transmission shifts great (less than a year old)
I also have a Diablo chip that came with my truck and when I plug it in it drives great too. No issues at all. So is it my TW chip or my truck?
