Okay so I'm finally going to get my +2 timing done tomorrow and the guy was telling me he could also move the RPM by 250, does anybody know if that helps? I'm not really sure if you was talking about idle speed or top end. But does anybody see a benefit in either? 03 FX45 . Always running 93 octane and just put in new Denso iradium spark plugs.
