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.
I suppose, however you have first hand experience that they dont do that in all cases.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 secret
Problem tuner is having is that I’m at 15psi @ 20* and it’s leaning out.I see my estimate of .5* per psi was right on the money.
12 psi total timing of 23* your there.
Tuner didn’t say...42lb injectors and 340lph pump so I should be fine on both.Do you know what the injector duty cycle was? 55psi on the rail is nothing really (40 base +15psi) if it was leaning out your either out of injector or out of pump.... the stock rails will easily support what your asking of them
Cobra intake and Edelbrock performer headswhat Heads and intake are on it ?
I agree it shouldn’t be running out of fuel . I made 435 on 7.5 psi with a old school a trim with those injectors, pump and stock lines and rails .
I think a 3.33 would do what you need . Seems something in the intake track is becoming a restriction thus making all that boost . Be it the heads or intake itself .
I had this issue with my 170s on my stroker with the ysi . 3.12 pulley and a 8 inch lower would get me to 22psi or better if I stayed in it .
3.33 would make around 15-16 on mine . Case in my story is it’s a measurement of restriction . Once something becomes the brick wall it makes killer pressure .
