Sorry another 408 hp guesstimate (choosing Fitech system)

Keep in mind the limited hand held tuning matrix. You CAN laptop tune, but word on the street your better off with another system if your gonna race it and want to get the absolute BEST out of your engine. You seem to get what you pay for. Holley has a nice system. You could also Megasquirt it. Seems that if your gonna do EFI, it might be nice to think about multi-port.
