New PCM

[SFsGT03]

Got the new PCM installed today. Just on the way home I could tell a considerable differance in the power. It pulled more agressively through the gears. Stage I or II next. Cant decide.

On page 4 of this topic under GTSteve is all the info if you need to find out if your GT is coverd by the TSB. I had a slight miss but not all the time and the dealership finally replaced the part. Had to actually get the TSB and take it to them though. When I took the TSB to the service manager he said "Oh, I thought you meant something else". They have to fix it.

SFsGTO3, did you have to write down the tsb number and show it to him? or did you print the tsb and show it to him? if you did print could you tell me what you printed so i could do the same. my dealership is giving me the runaround saying the mis is a rev limiter. thanks.

got mine 12-05-03 and love it and does inprove everything.
the thinh i need to know is when they flashed my new pcm they had to do it with what they called the california flash.This may be why the mpg go up as the eng is now set leaner . and if this is so the add a boost controller and you could burn a piston does any have any info on this?

ONYX, the # is 1802903 and tell them your car is missfireing at 53 to 5300 rpm, they will ask what is it doing . answer the eng stops running for a split second then run again, and the TSB 1802903 replaces the pcm to correct that. if you can't find this and need a copy, i will fax or maybe e-mail (if i can scan it) i will send you a copy. amx1397@aol.com

For reference:

Have the dealer run your VIN number to determine if the TSB affects your PT. If your car is covered, the dealer must change the PCM.
