In the future could I upgrade the chip & injectors and go 7 or 11 psi with a pully & tuning? Also could I retrofit a used kit from a 4.6 without major difficulty?

Its alot of money to spend for just 75 hp. In my opinion your not gonna get 75 more hp from just putting on a 5# blower kit. Contrary to what many people think you need to some tuning to the car to get it where it needs to be.
With a correctly calibrated MAF, one range colder plugs gapped lower and some half decent tuning I dont see why you couldn't gain 70hp from a 5# blower.
