Over the past 2-3 weeks my truck will not build boost under any throttle unless it is wide open. Usualy it would load up and spike to 10 but now it just sits at 0? any ideas or places i should start with to look for the problem? i was thinking a busted vacume line but i still get boost at full throttle which is weird? thanks for your help in advance

 

Is it a problem with the gauge or the supercharger?

 

all the time or when u get on it

 

Well the truck will go to 0 at part throttle then if i floor it the boost will build but slowly? all i have is a chip, 4lb, maf, and t/b.. could the charger be broken or the intercooler clogged?

 

what year how many miles?

Could be clogged intercooler, i suppose clogged air filter. Uhhhh, thats all i can think of. How does the power feel dispite the gauge? Does it feel slower?

 

the blower has around 55k the shortblock has about 12k and got a new intercooler at the 12k. the power feels slow sense im not makin any boost. I herd about a wax coming off the rotors of the blower does that sound right?
