My first dyno numbers(pic) Here is my first dyno, I had it done this saturday.
The car is a 98 Trans am, A4, 12 Bolt with 3.73s, Crane 1.8 Roller Rockers, Lingenfelter GT-1 Cam(218/229 at .050), ORY, Random Technology Exhaust, K&N Filter, High Flow Bellow and a LS1 Motorsports lid. THe car also has a 3500 stall converter, but its is pretty tight, so I don't think its hurting power much if any.
THe dyno seems to be reading a little bit low for my mods, what do you guys think.
I'm thinking that headers should really open it up along with leaning it out a little bit.
Any suggestions?

ya your peak numbers are a little low....long tubes will really help, port your TB, and maybe and LS6 intake, and a tune youll see 360?
but its hard to tell because your dyno started so late! 4500? should have been at 2000-2500rpm! hard to see your TQ curve...id say go somewhere else and post a diff graph? 2000-6500rpm......

12.0:1 is way to rich to get the car at max power potential. get it around 13.0 or 12.9 ... you'll run a couple of points leaner on the street. Thread Starter

Thanks guys, the reason the graph starts so high is we had no way to lock it in gear, so he dynoed through the gear, that little slope at the start is from the previous shift.
