well i took the car out for a drive, and when i hit the gas (i mean like floor to the ground) it takes forever to go from 0 to 25 mph, i mean in every gear, it just happened today & my boost gauge reads from -5 to 0, it doenst go past 0 at all, i was at a steady 12 pounds, i checked my mbc and everything is fine, what could it be? its really starting to piss me off, thanks Jesse

check your compression.

Also, you may have a bad turbo. Check for shaft play. Is your car smokin at all?

no it doesnt smoke, i hear the turbo spool and all, it just not building up boost

Can you get a compression test? Sounds like you may have a bad piston or ring.
