Had my 1998 Trans AM Automatic (A4) dyno tuned this weekend at 21st Century Musclecars. John, the owner, is a great guy and his crew is second to none. Everyone was very friendly and made me feel welcome as always. I highly recommend their shop if you are in the area and even if you are not it is well worth your time to check them out. They had several high horsepower and high dollar cars on hand to meet anyone's fancy.

Breakdown:
1998 Trans AM
Automatic (A4)
3.23 gears
92,000 miles
stock wheels
stock tire sizes

Only mods are:
MTI lid w/ K&N filter
smooth bellows
ported TB
NGK TR-55 plugs
MSD wires
Kooks LT's w/ catted Y-pipe
Corsa premium tip catback
21stCMC tune

Dyno Results:

329 HP / 337 torque

I was pleased given that my car is a '98 Automatic w/ 92k miles and still equipped with the stock '98 heads/cam/intake and minimal bolt-ons.

What do you think?

Thanks in advance!

Thats great! I hope my car puts down those kind of number, we have nearly the same mods. But by the time my car goes back on a dyno its going to have a converter so I will be happy with anything over 300 lol
