Come on Bro! We're talking dyno numbers, push it to the MAX and print the brag sheet, then dial the car down and keep those numbers secretI estimate with 93 octane and intake temps below 160* the tuner will run it around 23* total timing at 10psi or less. this is roughly .5* retard per psi from a stock A9L curve of 28* total.
If the timing climbs above 25* total at or around 10psi on a street tune with no meth injection i call the tuners common sense into question, will it make great numbers on the dyno? yes. Will there be a nagging sense of what if I get a bad tank of gas? yes.
IMHO on a street tune with boost above 8psi keeping the timing below 23* total is a safe bet and will keep things together even if you get a bad tank of gas.
