well you need to clarify, is this on stock seq. twins?


other than I guess running a bit rich since you should be at a higher boost.

No. The ecu has a map based on rpm and boost level.


You are getting 7 psi because the wastegate is allowed to open at it's actuator pressure (7 psi). This certainly won't hurt anything!

First time I took my car to the track I set it to run 7 psi just because I wanted to take it easy on her and make sure everything was running good. It's certainly safer to beat on it at lower boost than higher boost because slight issues with tuning won't manifest themselves as a blown motor
