To4e,60 trim compressor trim/ turbine housing A/R
T350,76 trim 0.60 housing

exhaust housing T3: 0.82

strong boost Onset rpm 4500-6000

The boost should kick in 1k to 1.5 earlier than I listed but that's when all hell breaks loose & a big fat surge of power will be felt.
that should be good for Approx 400-500 hp.
