Already did a search which did not reveal useful info. I have 255 lph fuel pump, head studs, and cams. Im currectly using a Greddy profec B (tuned by another tuner). The MBC is set to a 50% gain which looks like 18-19 psi on my gauge. How does 23 psi sound? safe? Must I now re-tune on the AFC with a new boost setting?

thanks
