Default just a reference guys...a 5 bar fuel regulator on stock injectors and more

is going to put your long-term-fuel-trims at around -14 to -15% rich. idle will be still around 0, but maybe a bit negative by a percent or two. at wide open throttle, you can start tuning from there and leaning out the primary fuel if you want with giac mobile tuner, apr v-tune or revo lemmiwinks or whatever else is out there. personally, i target around -7% rich.

just figure out what's fastest for your car. log 026 and 027 to be sure your knock voltages are in the high teens, low 20's. knock gets saturated around 29.835. try not to hit that frequently, if you bounce off of it from time to time, it's ok. you can either: add fuel or subtract timing to reduce your knock values. listen for any audible ping as well. fwiw, i've run some cars up to the limit and haven't destroyed a motor yet.

in block 031 log your wide open throttle voltages on the primary sensors and be sure it's around 0.8V+ to redline. anything higher than about 0.95volts is going richer than what i'd like to use.

(edit)...On stage 3- cars, a rough guideline at around sea level - 1000' above, you'll pull around 300 g/s of air on k04's at 15 psi. try to keep the maf at around 315 max. watch everything beyond 16-17psi as you may run lean on stock fueling and 5 bar fpr.

hope this helps you guys tune up your cars...whether it's on k03's or k04's or whatever stuff you run.

Default Sage advice. Wasn't sure about knock saturation value!

My favorite "tuner" quote, now deleted:
"If you had purchased our kit you car would still be a nice 2002 S4 instead of a big pile of blue garbage." Bob@strat. describing BuffaloNogaro's car.

Do tuners lie?

FOD kills.
