Unhappy
Went racing this weekend but was dissatisfied with the time that I ran. Mods are Flows, Undersized pulley, Pro-M mass air and custom chip from a guy in Austin Tx. Times were:
13.70 @ 99.73mph.
Truck is making 11psi but when it shifts it seems to lose the boost.
Any IDEAS?
Very happy with my 93 L. Roller tip rockers, Flows, B&M shift kit and 150hp NOS. other than that it is stock with 83,000 and ran a best this weekend of 12.94 on the brakes.

Sounds like you might be bumping your rev-limiter which kicks out the boost. Your chip **** points and rev-limiter need to be about 1000 RPM apart. This insures you that it won't bump it a WOT. Also if tires break loose and truck shifts to early it will feel like the same thing. Hope this gives you some idea.
