low boost....its all about the drive press

alright so maybe youve seen my posts bout not making enuff boost and my truk is the typical vp pos...

after a yr of diggin for the unknown i have come to the conclusion that i didnt have enuff fuel due to a part number mixup with my vendor..
kinda came to this concusion by acc but it helped me to find the issue

the vendor did help me with my problem pretty well since i had run the wrong inj for about 8 mos til this came to light...but it was thier mixup and no fault of my own...

i took out the inj i felt were wrong and installed the new ones and all i can say if if you havent got enuff fuel you will not make much boost. i was struggling to make 32 psi and after upgrading from a ''75'' hp inj to a ''125'' inj the boost guage not only races to the peg faster but blows right on by 40 psi that it had never seen before.

just a little info i have found out the hard way

I had the same problem with my custom pump and the throttle, I had made a big set of twins for my engine and couldnt get over 20psi. In the end I had to fix my throttle travel and now can easily peg my 60psi boost gauge.
