Dual TBI 454 8-71 help needed

[a78turbo]

I am working on putting together a 454 with an 8-71 blower, 0411 PCM, and running dual 454 TBI units. Has anyone done this sort of setup, and could anyone give advise on what would be needed to tune the efi system. Is t worth trying to use 2 TBI units for this project? Any help would be greatly appreciated.

If you used two of the Holly TBI units there would be 8 injectors the
ECM wouldn't know the difference.

Sorry, this might be too late. But I'm almost done with my 8-71 454 with dual tbi units. the first contact needed is to Bob at dynamic efi. for about $500 i bought a completed new ecm. this reprogams the computer to properly handle 4 injectors (2 per tbi unit) and he can tell how to properly wire it. he has been helpful for me, and has answered every question really quickly. I would have given up if not for him.
[email protected] is his email.

lemme know how it goes.

what l31sleeper said, might be true, but you have two iac, and two tps, so there are those considerations. my truck was an original tbi truck, and needed the new code to handle the extra 2 injectors.
