417LSX

Im looking at purchasing one of these for my new build and was just wanting some feedback on what people thought goods and bads of each system or what might be a better fit for my application. Im currently building a 414 nitrous motor capable of a 300 shot with trickflow 245s along with a 700 lift solid roller cam. Any help would be greatly appreciated.

Thanks,

There is a TON of info and alot more people running both systems on yellowbullet.

Look in the Electrical section.

I work with both. I prefer FAST to either one myself. Any of them will get the job done. I just tuned one of the new GM COPO factory race cars (427" NA) with the new Holley Dominator system. Some engineer at Holley sent them a couple of different calibrations that were undrivable. I would not rely on them for a baseline calibration to get started. As far as customer support, amoung other things, I would recommend FAST. Many NHRA Stock & Super Stock racers use them. Several switched to FAST XFI the past year or so.

Good luck.
