Was driving, had normal 16psi and suddenly when i got on it once, it backfired and now is only base boost 8-11psi is what i'm getting.

what I have done......

checked, rechecked, and recheckedchecked vacuum lines of which are all sicolone hose anyway...NO CHANGES.

tried two different WG selenoids of which i KNOW work for sure....NO CHANGES.

adjusted WG rod both ways at multiple settings......NO CHANGES.

tried differnt settings on ultimate........NO CHANGES.

checked turbo/ic pipe and IC/TB connections........no changes

checked all electrical connectinos such as WG selonide etc......no changes.


Can someone else give me some ideas here? Is there a fuse that could blow or something? Any help pleas as i'm out of ideas and stuck with a base boost truck.

TIA

Ok this might be of some help as i had lost boost from 14 to around 8 or 10lbs only and would start goin lean if i pushed it harder.
My problem started when i ran out of gas till the very last drop, i filled it up again and didnt pay much attention to it untill i raced it a couple days later. By then i didnt even remember the incident but i was worried and checked some of the things you did. I came to realize that if it was goin lean on hi boost, it would have to be the fuel sistem, i checked everything and changed the filter and voiala, 14 lbs again.
I had to change 2 more filters since then everytime i notused my boost was goin low again. I guess the previous owner kept the fuel level well above a quarter and me and my scroungy budget can only keep it half full at its best.
Good luck.
