Hey guys wanted to know if anybody is running JB4 on a B48 with upgraded turbo.
Going to run BM3 Flash and get downpipe soon but just had a son so taking things slow
Definitely looking to get upgraded manifold and extra
but this is the current setup

Haven't dynoed the car yet
Also need help raising the boost in JB4.

You can try to customize the MAP and set the pressure in units of 500RPM
