This morning's commute saw boost gauge go to 10psi. Tried it again. Yep runs to 10psi.

It's aways stopped at 6-7.

Wastegate? BOV? Stock internals. I don't want to blow this thing up.


Car was EvilMonkey's car, well maintained - has front mount intercooler w/ relocated MAF and TurboXS BOV, car had never seen above stock boost.
 
your wastegate has taken a dump. replace it with an ATP Wastegate. Don't bother with the OEM one its crazy expensive
