Maybe I shouldn't be running stage 1+...
Yes....that sounds like an aftermarket intercooler then.

Other than the excessive wastegate duty cycle I think that tune is working quite well on your car. The boost and timing targets are pretty conservative.

What gas are you feeding it? 94 octane or 91 octane?
