Bolt on 1998 Trans Am. Trying to get the chart, may take a day or two to swipe off the computer at the shop.

Put down 346RWHP @ 5200 RPM.
It lost power at 5200 on the first pull (cold).
The next two pulls it peaked at 5600, but only at 345 due to heat soak.
AFR is sitting at 12.5 to 1.
The numbers look decent for a bolt on 1998 car, IMO.

Pretty good, especially for a 98'! M6 I take it? Those numbers are better than my old cam only A4 98', given it was a slouch before the heads, it did 342/350, lol. You could lean it up a little more and probably get a lil more power, 12.5 is pretty rich for a basically stock car.

I lost 2 HP going from 13.5:1-12.5:1.
I did this on a humid warm day.
Yes the car is an M6.
