STS 2bar tune numbers
STS 2bar tune numbers Got my Custom Rear Mount dyno tuned yesterday and I am a little confused with the numbers. Final numbers for the day where 505 ftlbs. at @4400 rpm 
and 420 rwhp at around the same rpm. 11.7-12.2 A/F all the way up This was on a dynopack dyno. Peak tq and hp where close to the same rpm. 8.5 psi at 4400 rpm, the boost then tapered down to 5psi by 6000 rpm. I have a $hitty bleed style boost controller and think that may be the problem. I did get higher hp numbers, sometimes the boost would hit 8 and stay all the way up till red line??? I think 450ish. Also hit 10 psi once and 540 ft lbs before shutting down from KR. Also was only running 13-14 degrees timing. Maybe false knock, I didn't want to run them de-sensitised, I'd rather be safe, any got comments ideas? I'll try to post a graph soon
