Hey AL just had my car dynoed and they guys out here didn't see any problem in turning boost up to 23psi and tapers to 20 at redline. My Air Fuel was 12:1 ish from 2k to 3k rpm and tapered down to about 10.5 to 1 from 5k to redline. Is this bad, they claimed it wasn't? Should I just turn the boost down to 20 and play it safe? thanks allen

By the way made awesome power 316 HP 350 TQ!!! Even at 20 psi was 307HP 341 TQ. thanks again

 

On 91 octane - peak boost should be 20.5 psi - 21 psi and falling down from there

Excelent results BTW !

 

how about 93?
