I get no boost on first ...5 psi on second and 10 psi on 3rd gear.
I have a boost control Joe P. and no stock Boost solenoid.

You shold be able to make boost in first gear. It sounds like the wastegate might be stuck open or you have a manifold leak.

ditto... i gotta really punch it to get boost in 1st though


I rev it to 5-6 grand and nothing goes to 0 and thats it... second gears sees a little more....third sees a little more and so on....
BOV leak?? maybe my MBC is shot.....I set it up for 14 PSI last summer and I did not touch it since and now am lucky to get 10 PSI....
 
I dont' see it being the boost controller. If the boost controller was shot it would be the same problem in all gears.

Pressurize the intake and look for leaks. Make sure your wg flapper is sealing completely. Look for cracks around the wg hole in the turbine housing, and make sure you don't have any pre-turbo exhaust leaks.
