I have only found one OS for 2002 manual LS1 Camaros. Does that mean that the Z28 and the SS run the same exact tune?

That would require that the extra 20 horsepower is simply from a freer flowing exhaust, ect. and there is no adjustment in the calibration. Am I missing something here?

Also, I am pretty sure the stock file I pulled from an '02 SS had the same Cal / OS # as the Camaro file available on TFD.

Yes.

And also the Pontiac Formula, Trans Am, Trans Am WS6.

Yes (and marketing). Correct.

:muahaha:

Thank you Joe!! Here is a very basic log of my friend's SS. I am trying to get it dialed in for intake and exhaust. Full throttle was not possible due to rain.

I know many parameters are missing, it was basically a quick test.

I know I really need those, will post them up soon! Car just went 8.4 @ 85 in the 1/8 last night. It has to have more in it.

A full tune even in a mostly stock car,especially an A4, is a night and day difference.

Thast doing pretty good for a stock LS1 car. That equates out to a 13.1 et in the 1/4. No stock autos run that quick, thats optimum condictions LS1 6 speed territory.
