I've had both the Procom and the Firestarter. Procom has nice giddy up but is fickle to start and dial in. The last one I had shat the bed, just would not start the bike any longer no matter what Voodoo I tried.
I've had the Firestarter on my 790 with no engine mods for about 600 miles so far. Pull the choke all the way out in the morning and hit the button, spins over hard and fires right up.
Runs well, no flat spots etc. I did need to adjust the idle somewhat and lean in the air mix screws as the bike smelled a bit rich.
Basically the Firestarter is plug and go with the longer wiring harness for relocation purposes.
TTP Firestarter would be my choice again.
