I went and got my car dyno tuned about 3 weeks ago.It is a stock gsr motor with a sc61 turbo with all the supporting mods like rc550 injectors and Aem Ems,etc.So on the dyno they kept peaking the boost up to 15psi on a stock map sensor.So eventually they set it to 6 psi which was good enough for me.But my question is 2 weeks after the tune my car started blowing steam/smoke out the breather in the valve cover?Car would not stay running after the dyno tune come to a stop and the car died then had trouble starting.Then the motor blew 2 pistons melted 2nd and 4th cylinder also the ringlands were broke on them.Then when I took the pistons out all 4 of the pistons the ringlands were broke.My question is would 6psi break all 4 piston ringlands?If not do you think the motor was sh*t before I boosted it?Because I didnt think boosting a gsr motor would cause ALL 4 piston ringlands to break.This sucks!!!
