Got the gsx tuned today... It didnt turn out like I wanted but its fine for now. It made 330awhp on a mustang dyno at 24.5 psi. Emery at stm did a good job and was cool as $hit about everything. But the car still has its issues that will be figured out. The main problem im having now and has happened a few times, is when I boost the car the wastegate opens and sometimes it closes and sometimes it stays open...
