I've had Accel LONGER -- and have spent HUGE money on tuners - which would include towing to multiple states...
If anyone wants the pile -- it's laying in a box - along with TWO ECUS - TWO dual syncs and a gaggle of wires the size of which would choke a horse.
I put on a FAST EZ EFI on my multiport 8 stack 406 --- and have never been happier with EFI -- and that goes back almost 10 years!
Can it tune itself and do all and be all... hell no! Can it run a nice little 550 ft lb of tq 8 stacked 406... OH YEAH BUDDY! And it cost less than ONE DYNO trip.
