I’m just gonna stick with 93 for this summer. If all goes well… on high boost ,somewhere around 18psi, I think il make somewhere around mid 500’s, but like i keep telling everyone. I really don’t think il turn the boost up this summer because I just want to enjoy the car and it should be making low 400’s off wastegate spring.
