tranny issues after stock tune

[joeshmo22]

i have a 94 formula the car previously was tuned with trick flow heads, pacesetter lt, no cat, and cam. my friend baught the car and pulled the heads, cam, and headers off and flashed the stock tune into the computer. i got the car from him and with the stock tune my speedo is 10 mph off and the shift points are messed up as theyll bounce off redline twice before it will shift.

Car has differnet gears in the rear end

the car has the stock 2.73 gears never been changed

[Chris]

Im putting my bets on that though.

i pulled the cover to make sure what gears they were. still gm 2.73 but do have a set of 3.42 to put in. could the tune have been for a 3.42 car instead of 2.73 car if so where could i get it tuned at.

Have your buddy reflash it? If you know there are 2.73 you can send the file to someone on here to look at it for you if you have a cable to pull the tune, or you can send it to a place like pcmforless or the like.

well he got the tune from someone off here. and ive tried to get him to look at the tune but hes being kind of a dick right now. ive downloaded tunercat but have not baught the cable yet might just send it off to pcmforless after i put my 3.42 and lt on.
