Dear Jim N., I don' t suppose your suggestion has anything to do with your recent stock purchase,ie. "Fast" ? 1,800 cfm....Really ? The idea of using as much oem. equipment, as practical, so as not to sell a kidney, appeals to me. It's jus a lil' hemi, and a smaller budget. lol, roverman.

Hey Art,

Talk to a good injector rebuilding shop. Motor Man and R/C come to mind first.
They should be able to rebuild and recalibrate your injectors for you.
Or you can just leave the injectors out for the same effect!

Cheers
Fred

Fred and clan, "Xtreme EFI" says GM tbi's not compatible with E85/alcohols. Accel "port" injectors are, with up to 160lbs/hr,(low impedence).Where get/make tb/tbi's to take port injectors ? I like concept of injectors"under" the slide plate/butterfly.How bout' oem. tb's mounted vertically ? Thanks, roverman.

Just a "little" more, please ? Evidently NOT. Why ? It's looking like Megasquirt III might be better controller, ie. cop.,E85 and supercharged ? Thanks, in advance, roverman.
