Fuel Injection Recommendations

If you have something wild enough to run a tunnel ram and 2x 4's I would not screw with the TBI systems such as FI tech or Holley Sniper. I'd want to go right up to a port injection even if it's batch fired instead of sequential. Just my opinion. There are ways to make 2x TBI systems work together and guys have done it. But the HP computer used with the Holley "larger" systems are much much more versatile.

So far as I know, Holley has basically 3 "computers." One is the built into Sniper one, next the HP computer which is used in pretty much everything else except Dominator, and then that last one which adds a lot more capability over the HP features.
