If i change my injectors to a higer # will i need to hook up the FMU. Also what size injectors do you reccomend for a 97 lt1 p/p heads/intake Hotcam bolt on stuff. and vortec v-1 strim 6-7 PSI boost

I may be wrong here, but instead of messing with the FMU, why not go with a Boost Refrenced Fuel Pressure Regulator? A boost refrenced FPR should do the same job as the FMU, but it will bolt right where your stock FPR is.

1:1 rise in fuel pressure per psi with boost

Your main issue with going to bigger injectors will be tuning. With a boost refrenced FPR for every # of boost you make it raises your fuel PSI by a #. Same principal as the Vortech FMU, but it gives you more headroom for future mods.
