Although still lower than spec Arrrghhhhhh, I am getting max boost of 9.5 psi in 3rd and 4th gear. However, in 5th gear, it peaks at 10.5 psi.....Anyone knows the intricacies of why?
Secondly any further suggestions to get my (89 SPG) running spec 12.7 (?) psi boost?
I have set base boost (5.5psi), new NGK BCP 7EV, set timing, checked all vacuum tubing/air supply hoses/plumbing, new airfilter, changed intake vac hose grommets, new distributor/caps.......checked hooter valve and waste gate actuator, checked knock sensor, pressure sensor with mityvac....
Am getting frustrated....I have a new 3 bar FPR and resistors ready for red-box APC upgrade, but cannot do it yet until I have car in spec on standard equipment...aaarrrrghhhhhh Help!
