43# is the highest I have seen in my case at BPU as well. It goes negative after that.
For those reading this thread I am taking about the MAF #/min flow rate and NOT the percentage that your AFC reports. The AFC numbers might be interesting too but I am not sure how comparable they are.
Grant from talking to Steve97TT 43# translates to around 400 bhp without transmission loss numbers. Did you ever dyno your car at BPU?
I think I got the latest version of obd-2.com software to work so I am hoping to see if 43 number can be exceeded at BPU.
I just tried the new version of the software and the highest I have seen 43.164 lb/min. Using the calculator on Steves page that translates to 470 crank and assuming 20% auto loss 376 rwhp ;-). If it wasn't for the nasty 91 octane gas it could be higher.
Gotta love OBD2 when you can estimate your RWHP using it ;-)
So now that I know how slow I really am time to upgrade.
