Default Dead spot in gas pedal

My truck always had a dead spot in the pedal where it seemed like if I didnt floor it nothing was gonna happen. I got my SC tuner and that fixed most of it, but now I feel like its back and even worse at times. While on the highway if I wanna speed up I have to press the pedal 3/4"-1" to get it to downshift and speed up like 5mph. WTF!!!!!

So it bogs or just doesn't do anything in this "dead spot" ?

Are you in D or O/D?

It doesnt bog it just acts like im not even pressing down on the pedal, and when it finally says "O I should be doing somthing" it downshifts and takes off and alls I want to do is close the gap between me and the guy in front of me, not run him over. Its in D I cant choose OD. If i put tow haul on it just revs higher and takes off everytime I hit it, no problems there.

I kinda have the same problem. I haven't been able to dial it out with the Predator and it has me kinda stumped. I cleaned my TB (it needed it) and it seemed to be better but not by much.

That sucks. My TB was bad also but I try and clean it whenever I clean my filter. Can the TPS sensor be dirty?

Sounds like a Transmission issue not a fuel system issue. If it will work fine in tow mode then it is not detecting the signal to down shift properly.
With out the down shift the motor will not rev. Since your in an overdrive gear crusin the motor is spining almost half as many RPMs as the rear tires. I'm not to sharp on the Chysler overdrive transmisions but I think they are electric over hydralic systems so your best bet would be the transmission shop.
