I messaged David about something I'm working on,a dual tbi for my 451. It's non mopar. I scrounged up a pair of G.M truck tbi,wiring and computer. Why? Simple,it's widely available and easily modified.
They told me that they have experience with this set up and have done it before. Affordable will mod the computer and wiring harness,I can rebuilt the tbi units myself.
But always looking to do things my way I found a chip modding wesight. I think it may be possible to burn a new chip that would control both tbi no problem,but not having any experience with this area would make it a black hole for me.Will likely just go with affordable,when I can afford it lol..
