How's my Dyno pull look?
 

We had a dyno day and I was very happy with the 85* heat and high humidity to pull 315hp and 327 tq, back to back. A/F was 11.5. Dyno operator said I could lean it out some more....
My cars an 2002 WS6 A4 with an SLP lid, Borla Y-pipe, and Hooker cat back. That's it for engine mods. Only 4000 miles.
Most of the M6 F-bodies only pulled 300-310 hp, with the exception of a 02 T/A CE M6 that had a SLP 85mm, lid exhaust. He pulled 320hp and 334tq.
A 99 WS6 M6 with an LS6 intake and many bolt ons pulled 319hp and 319tq.
So I figure with the 20% loss through the A4, I'm doing great.
Take a look at my tq curve, very flat.
Should I worry about the small dips and peaks along both lines?

You have a very strong car for that A/F ratio. Lean it out to between 12.8 and 13.0 and you should see another 10-15hp.

Good #'s!

Thanks guys. I had a ported MAF on a few weeks back, but we had a hot spell in the 90's* and while on the highway I punched it. When I got above 4500 rpm's, I thought I had a plug fowling out it was pinging so bad.
What setup do you recommend. Maybe the Pace 85mm with LS1 calibration?

2001's and 2002's seem to respond really well to the GMAF. I had the Pace MAF and my A/F fell all the way into the 10's, I put the GMAF on and got 12.8 - 13.0. See if you can borrow one from a buddy so you can try it before you buy.

Don't waste money on an MAF. Get custom programming instead.

Re: How's my Dyno pull look?
 

That's a pretty good dyno. I dyno'd my '02 WS6 A4 at MTI when I had had it about 3 months. Only mods were a lid and the Corsa exhaust. Oh yea, had the screen out of the MAF.
317.3 HP and 338.1 torque.

We're about the same on HP, cars vary 2-3hp between dynos and conditions. Your posted TQ is higher, but on A4's unlsee your looking at the lock up portion, you get high readings. If you look dynop1, mine was 391 tq.
I'd like to see your graph for comparison.
Thanks-

They didn't check my A/F ratio. Numbers are corrected.

Thanks for posting. That's about what I expected. The graphs are damn near identical.
Yours is a bit more choppy, which I expect is due to the ported MAF. I wish you had a A/F ratio so I can see what that MAF is doing.
Torque spikes-you got to love them.
Some of the people were freaking about my 391...
Thanks again.
