engine cutting out

[ryanr]

i just installed my fu chip and just the stock, high idle, and whisper tunes seemed to work right but the 65 tow, 80 performace, & smokeshow seemed to not be quite right. in the 80 performance and smokeshow settings when i shift at higher rpms (2600 and up) when i go to my next gear it takes a full second for the pedal to respond then all of a sudden it takes off. sometimes when driving at light throttle the engine will start cutting out until i let off the pedal.
i then pulled the pcm back out thinking i didnt clean the contacts good enough. i cleaned them again and put it back in and now the tunes seem to be working power wise but im still having the cutting out problems while driving and shifting. does this sound like i still not have the contacts clean or could it be something else?
any ideas would be helpful, thanks
