...here is a dyno graph of my car that I found, the only difference between the graph and now (despite the 50k miles) is that this is in NorCal at about sea level, and all my data logs now are in LV at about 2200F above.

91 octane CA gas (Chevron I'm sure). I have no logs from this dyno run, so don't ask. But i've posted 003 / 020 / 021 logs from the same car at higher altitude in the last month.

This is on ATP's Dynojet dyno...

Wonder how much power I could extract out of a stock S4 with tweaks =P. I was going to dyno my car there but now that my car has that stupid turbo drill sound I guess I won't be dynoing my car until the new turbos are in.

People never believe me when I tell them the stock A/F hovers at high 13's to low 14's, nice post.

haha, i have a hard time with people believing me even when I have data to prove it.

What do people shoot for when tweaking? Is 13 to 14 on the rich or lean side?

AudiS4guy - NorCal

lean...i aim for 11.5:1 a/f ratio...thats where I made the most power.

Cool, thanks for the clarification

Yup. Stock runs relatively lean at WOT. I've seen it myself.

Captain Matt, I be

would you run a modded car that lean?

EGT's should be checked as well.
