hey guys ive got a 03 7.3l with 4" mbrp and the bully dog gauge tuner and also the banks compressor wheel but the gauge tuner with it up all tyhe way is tellin me its pushin 50+ psi boost. this cant be rite any input?

 

on a stock turbo and studs not a chance

 

If its telling you MAP rather then boost... Its possable. If your near sea level your MAP will always see 15-17psi due to just plain old air pressure... Then you add 30psi to that and... there ya go.

However the bully dog gauge should be taking that out, so you could be looking at exhaust back pressure...

but there is no way on stock injectors you are making any more then 30-32psi.
