So then what about the fmu that came with the star kit? WIll what i have be enough to support 15psi daily driven? And a recap on what i did. Racing a 2000 mustang cobra about 2 and a half months ago, i was smoking him bad on 10psi, my car stuttered just a lil bit right before i started to race..well i was so excited i didnt look down at any of my guages..and next thing i know im doing 140, i cant see anythying cause of all the smoke..and my car just died. Say good bye piston rings, but oh well. I just want me car back.
