I would love to be able to ditch them, one less thing to go wrong.

Just an opinion, but it seems to me that as long as modifications are limited to how many injectors are operating (in closed loop), i.e., no other mods are done except for porting, it seems logical that a prom with the appropriate tune should be able to operate two (instead of one) injectors and maintain the proper air/fuel ratio. Two injectors instead of one does not spell emissions failure; only the air/fuel mix would do that (all else being the same such as cam profile and timing, etc.).

But, this would be a question for Dom or one of the pro tuners out there. However, I'll be comfortable placing most of my "chips" on the square marked "won't affect emissions".

So, what do some of the tuner experts say?
