Could I get a boost expert to do me a favor and look at my spark advance? I'd like to know if it looks like I'm going down the right path.
AFR: Around 11.0 (93 pump, 0 KR)
Car info:
98 A4
Dart Pro 1 205cc (10.8:1 compression)
228/232 .571/.573 112
Fast Intake, 90mm LS2
BBK headers
160* thermostat
A&A/Procharger P1SC - 5PSI
Yank SS3600
3.42 rearend
I've seen several tunes where boosted cars just run flat timing across the RPM range, which doesn't seem to make any sense as it seems it should be starting high and tapering low as boost builds. With what I have now, I have good throttle response.
With my setup, should I be more aggressive with the timing and AFR (lean)? I don't plan on running meth.
Thanks for the advice!
