From some other guy:
stock compression is 9.5:1 on the KA24DE motor, boost to 12-13psi is fine, but going to 15psi is doable but with good tuning, past that point is kinda dangerous on pumpgas...

This is reasonable enough. A shop hit 401hp on a stock motor. TY hit 18psi and 360 (or so) wheel hp. Many people plug in a JWT ecu and boost to 12-15psi. And Scotts ecu > JWT.
