Anybody familiar with FAST EZ-EFI?

[leroy93lx]

We installed a FAST EZ-EFI system on a 426 Hemi Crate engine. Overall drive ability is good and highway speeds are fine but it has a slight stumble and seems lazy when you stomp on it to take off hard. It is suppose to be a "self learning" system but does have tuner adjustability. Has anyone every dyno tuned or even data logged with this system? We just did a clutch and rearend gear swap in it and think some fine tuning would really bring it to life. It has a Viper spec T56 and 3.91 gears behind it now. Weather permitting we plan to drive it to the Mopar Nationals in Columbus.

See if it has the option to adjust the acceleration enrichment values.

I'm sure it's similar to Holley efi and other stand alones. I'd give it a go. And I am a huge moparhead.

Sounds good. I will get with my Uncle and we will try to correlate schedules with you. Here is the "BlackBird" project in question

WOW! I am impressed! I would be honored to help you out with that. Last time I was in a superbird, it was one that I had done a complete restoration to it, and drove it at the mopar nationals. Then I handed it over to the owner. Car was hemi orange and beautiful, but a basic stripped down model with a 4 spd tho.
That is a beautiful Superbird tribute. Very nicely detailed. If only they would have made superbird convertibles, they'd have sold a ton of them.

Thanks guys. This car isn't everyone's taste but you can't help but like super slick black paint, a white hounds tooth interior and a HEMI! It started life as a real 70 Road Runner convertible.
