I ran my car at Thundervalley Raceway in Noble, Oklahoma last Friday and I'm really dissapointed in my car. My best run was a 13. 79 @ 101 with 2.1 60'. Reaction time was pretty good at .006.

The thing that I dont get is I ran two years ago with just a catback and was running low 13.7's and trapping 102 or 103. Now I have headers and dual exhaust and I'm running slower? Reaction time was better this time also.

There were a couple of other Trans-ams running 13.8's with one being stock and another having exhaust and a few other things. Could it be the humidity or elevation?

you would have to compare the DA from the last time you ran, it may have been a lot better (cooler/drier/higher baro) then when you ran stock.

Reaction time doesnt mean anything, the clocks dont start until the car moves so you could sit there a minute before you launch and the ET wont change.

Or maybe you need a tune with the headers if you didnt do it..

Also, was it even at the same track? Lots of variables to deal with, don't worry too much about it, it'll come around. Just as long as your having fun trying!

Get it leaned out, the stock tune is too rich, and i've heard it get worse with long tube headers.

if your running right now in this heat your GOING to run multiple tenths slower in some cases esp if the humidity is high

KP hit the 2 major points I believe.

DA can mean 2-4 tenths between runs without any changes, so you'd need that info to make a decent comparison.

A tune is most likely needed after the exhaust swap.

Any ideas of how many tenths a good tune will take of the E.T.?

that is my home track, did you have traction problems? i have hooked better on the street than at that track

Depends how bad things are. Witheverything in my sig minus cam, pulley, and tune, I was @ 304 HP. Stock tuning was killing me.
