ok here my problem, i got a new turbo ( a bd super b special) but mt boost gauge will only top out at about 20 psi. put a new gauge in and thats not it, no holes in the hose. only thing i can think of is the intercooler anyway i can check it or take it to a garage. any suggestions what else to check?

 

Do you have enough fuel to spool it? Wastegate adjusted?

If you need to pressure test you can make a setup with some pvc tubing caps and a valve stem.

 

Do you have a module that has a boost fooler on it or a stand alone boost fooler?

 

Forgot that part too! Thanks h.r.d. if your not getting any boost fooling your engine will derate.

 

Here to help my friend.

 

If ur not getting any boost then those could be ur problems if ur getting some boost with high egts u prob blew out a gasket somewhere or have a leak or crack in a hose

 

im still running it stock with no programers, im getting the same amount of boost as i did with the stock turbo. what gaskets do i check?

 

You need boost fooling or u will not see over stock boost numbers. Also need more fuel to get more air.

Yessir, bigger turbo on a stock truck will yield harldy anything because of fueling and boost reading derating your fuel output. You could throw in 200s and still not see good results without boost fooling
