Thumbs down FAST TB - Any1 Else having problems

getting the idle dialed in properly (day to day).

Like anything Im sure there are some people having problems, and others who arent.

Had the car re-tuned (ls1edit & dyno) yesterday and everything was perfect. Today I couldnt get the car out of the garage to save my life, idle was fine in 'P' - drive/reverse immediately killed the car. The readings were in the 100+ range on the IAC and 3.00 range on the TPS. Of course these readings are no acceptable and no where near what I saw yesterday at the speed shop (IACs were steady @ 40, TPS at 0.8/.04)

Just curious to hear from anyone else who has had similar problems, your overall solution or quick fix if one exists.

Seems most ppl are reporting this problem with 90s, has anyone had a problem with the 78s or does it matter ?
