87' Shelby GLH-S inconsistent Boost

About the Diag Codes... Problem solved. Just some bad contacts on the Solenoids.. As for the over boosting, That was bad Gas causing that.


Now my problem is this.. When I give it half Throttle the boost jumps to 6PSI and sits there no matter if I give it a tad more throttle or not.. At Exact WOT, The Boost Jumps to 14.5PSI and holds.. At least some of the times.

When Im speed shifting through the Gears, I Can hit 14.5+PSI in 2nd but 3rd 4th and 5th will jump between 9-12 PSI and cause the car to Surge a tad bit... Keep in mind this is only when drag Racing. If im on the Freeway at 65 and roll the throttle on, It will hold 14.5 Lbs till the Cows come home..

Anyone have any Ideas or have ran into this problem?

Thanks,
