im building a 383 to go in my 91 firebird and i really dont wanna go to carb for fuel economy reasons plus i dont want my ses light to come on and i would loose the lockup on my converter. but i was thinking would it be possible to run 2tbi units on 1 computer just splice the wires together and burn a new chip? i tried searching and whent through 17 pages of nothing in theory it should work the computer would just be sending the same signal to 4injectors instead of 2 but as i was told by some guys on afb you are the tbi gods so im at your mercy.
thanks

 

Sure it would work; but that's an awful lot of work to go to, when you can just go to the junkyard and get a TB off of a 454 truck and be done with it.

 

i will suggest it has been attempted but there are some issues. i believe i heard it will require a diff ECU and much more experience tuning than most of us have. plus a 454 tb seems to work quite well for those that run it. it can be bored larger to boot. but may not be necessary.

 

I would definatly opt for the 454 tbi or even a holley tbi, I beleive they make 4 barrels too.
