Ok, so I have an 87 Shelby Z and every time i open the throttle and boost up to about 14psi, the car will cut off the fuel supply and the little red overboost light on the dash will flash quickly, then as soon as the boost drops back down to like 10psi, the fuel will flow again... This is becoming very annoying, and im wondering how to fix this... I may have a vacum leak in the line running off of the wastgate due to the hoses all being so old and cracked and shit. So, If my wastegate is functioning properly, I should not overboost... correct?
