Air/Fuel Ratio
Dyno'd my S today with AEM V2 CAI Spoon N1 Single and Megan Racing straight pipe.
Pulled 217whp (temp corrected)
My A/F peaks at about 14.5 - but dips down to the high 12s at about 8600. Steadily in the 13s and 14s.
Do I need to increase my fuel supply?
Is the screw on top of the fuel line connector an adjustment, or just an attacher ?
Thanks!

your a/f ratio was getting richer as you got higher into the revs, as it should. and even if you could adjust the fpr on our car, it wouldn't do you much good. the ECU would just kick back the injector pulse to continue to pull the a/f mapping it wants to use.

Good then, that's reassuring. When I first put the cat delete pipe on, I was getting some cackle at the 8500 range and up shifting. Bet it was throwing fireballs! 
Not so much after the ECU "learned" it was there.
My biggest dilemna right now is finding somewhere to tie into the fuel for my nitrous wet shot - without drilling the rail or destroying the fuel line.
Any suggestions?
