Hey I'm selling a Accel D.F.I Gen 6 computer with the harness. You just plug and play. You use your factory 87 to 95 Ford harness. And the you plug the Accel D.F.I harness to yours. It Works great I'm asking for $550 complete. Comes with map sencer complete. I'm not thirsty to sell it for dirt cheap. So please don't try to low ball me. And please no tire kickers. Be realisticThis is a great kit. That you can tune with a laptop. And ajust your RPM limit timing curve. And so on you get what I mean. If you serious about buying it. $550 shipped and all. Only reason I'm selling is because I went with the new Fast 2.0 Stand alone set up. That does the samething as the Gen 6. But has a little more options. And a lot more money. I just lowered it from $650 to $550. But that's my bottom price. Listen This is plug and play set. Please don't waist my time tire kicking or BS with me. I'm a grown man. I'm tierd of everybody on here bsing me. If you want a working tunable set up and not brake the bank. Then get at me.
