At the wheels 320HP/339TQ stock? So I went to the local dyno to get some stock rear wheel numbers. Here's what I got on three separate pulls... #1 - 313/330 #2 - 318/337 #3 - 320/339. The only difference between any of them is that we took out the paper air filter on #3 to see what difference a "high perf." filter might make.
As far as I am aware, the only modifications include FRA (myself) and Flowmaster muffler (previous owner).
The graph showing all three pulls is attached. The dyno operator believes that my car has been tuned at some point based on the A/F numbers we saw.
From what I remember, the A/F was consistent mid-12s throughout the 4-6000 rpm range.
Have I benefited from a tune or do I have a "freak"? Either way, that is a serious head start for me.
My car: 2002 Z28, M6
Mods include: FRA, Flowmaster, 17" 275/40 Nitto 555R on Z06 Motorsports from Tomz Wheels

most '01-'02 dyno around 300-310whp. With a fra, catback and tuning, you might have another 10-15. Id say your right where you should be.
