What's a blown motor act like??? I didn't know some could still somewhat run when blown, but, I rev it to keep it alive and it runs bad. I only ran 6psi on it for a week, before that it was 3psi for a week. I only boosted out of control one time and that was the first day I installed the turbo and forgot to adjust the wastegate. But, I adjusted it and it ran fine the last 2 weeks before I ran into problems. It's a Star Stage II kit, t3/t4 turbonetics, with delta wastegate by Turbonetics, and Spearco intercooler.
