FITECH

Had a Go EFI Poweradder 600 HP on my supercharged 340. I had considerable issues with the RPM noise errors but I fixed that by shielding the distributor pickup wire with tin foil inside of a wire casing and wrapping stainless steel wire around it and running the wire to ground. I will be running this on my new stroker. I will say that although it is "self learning" don't think that it won't need any tweaking by you, it will. All in all once tuned they run awesome.
