not running eh?

1989 Turbo Trans Am #82, 2007 Cobalt SS G85
Definitely not. His step dad took it out for a spin and was specifically told not to touch the boost controller as we had just installed it and didn't have it tuned yet. Well guess what... he touched it. My bro called me telling me the story and how his dad said he DIDN'T touch it. However when i got there, boost was set at 27 psi when i knew i set it at the stock 15 psi. It recorded a boost spike somewhere in the 30 range. The car misfired and barely ran. Pulled the head off and found #2 and 3's ring lands broke and the exhaust valves burned about 1/3 of the face off. So new pistons and valves should do it.
