Hey, i am so close on closing a deal on an ATI Procharger kit, but from what i heard the '05 Z's were a little different then the '03's? Does this difference have to deal with motor, suspension, body, or what? I also heard the new motors retard timing differently then the 03's. Is any of this true, or is this guy bluffing. Ive read about so many blown motors with the ATI but hope i am one of the few that dont have that problem. Could someone give me the lowdown on this, thanks.

 

anyone know
