i recently had bolt ons put on and sct tune. car ran good before ecept for surge. i was doin high 13,s. after plenum/tb/and change from open air to enclosed system s/c and sct tune i took car to track. on 3rd pass motor blew. im wondering if it was his tune. valve is bent fer sure and im not positive about piston condition. might need new motor. i paid this guy alot of money to set my car up so i wouldnt have this problem and here i am. gonna have the car looked at by another shop but its not a speed shop. hopefully i can just do heads. if not ill be lookin for a motor. any help would be greatly appreciated. this forum has helped me alot before. ill either need a set of ip heads or a friggin motor. for his sake i hope i dont find out it was the tune lol. thanks
