hopefully the problems are in the tune. Well we all have a story...so here's mine....tell me what u all think.
I installed my cam, heads, intake, exhaust, and then had the pcm "mail-order" tuned just to get my car up and running to get it to the DYNO. Well, I wanted to get my gears and stall done before I did take it to the DYNO, so I went ahead and installed my converter last weekend...went to do the gears, and upon getting into the rearend we discovered the gears were already done..with 4.10s being in there. I couldn't really believe that...but since I hadn't gotten to drive the car much I guess it is plausible. I leave those in. It is here that I must say that the computer upon having it tuned the first time I find that it thinks there are the stock 2.73s in...this is obviously screwing up odometer and speedometer...but would it screw up anything as far as driveability?
OK, so I go ahead and drive it...not mashing it much since I want to protect it until it is tuned good...the engine stalls EVERY time i approach a stop or even slow to a point where I wouldn't be stoppin...right around 1k rpms...I assume this is due to a change in rotational weight from the new converter, but I wasn't sure It would do it every time. Runs very strong though. Question is, after its tuned..how often should it stall...i suspect it might some..but how often? is my problem related to a tune?
