3.8 SFI Turbo vs 4.1 XFI Turbo..

Well as stated above, I seen a GN with a badge that said 4.1 XFI Turbo.... I know what the 4.1 means, its just what does XFI Turbo mean.

XFI is the aftermarket engine management system. F.A.S.T. XFI

Coach, Thanks that makes sense, I just thought it was a certain Head or a porting of the head... I must have it confused with something else.....Thanks for the info
