Car: AR-60 turbo, KB Intake/Exhaust Manifolds, NGK UR5's, electric fuel pump...reads 40-43 psi @ idle and 55-60 @ wide open, Lucas Red stripe injectors, nice intake w/stock maff
had it set at 15 psi with old skool KB chip from original owner and it would always ping a few times at WOT near the shifts, even with a 95-96 octane mix (pump 91 & Sunoco 100).
Put the new TT chip in tonight and finished off the 1/4 tank of 95-96 mix. The car started right up and sounded great, no rough idle or hesitation at all. Drove it for maybe 5 miles at 0-50% throttle feeling it out and finally ran it through the gears. Couldn't hear any pinging or detonation and pulled strong @ 15psi for many pulls
Success!
Thanks TT!
Do you think I will have to turn the boost down with 91?
