Stage 1 options....Dyno or Power Vision?
I'm going to order:
Vance and Hines Dresser Duals, Rinehart 4" mufflers and a Harley Stage 1 AC.
-or-
Vance and Hines Dresser Duals, Jackpot 4" mufflers and a Harley Stage 1 AC.
I just have to decide on the tuning route.....
I think the dyno is over rated any ways. people spend hundreds for just a couple HP. set it up so that the air/fuel ratio is about 13.4 from idle to 3000 rps and then pour the juice to it and run a 11.8-12.5 to red line and should be some good HP made.
I am intrigued by the Power Vision, but not enough to replace my Super Tuner just yet. Is the PV a piggy-back device (like the Power Commander) or is it only used to upload to the ECM?
Yeah, I know it can be left connected to monitor vitals while riding.

I believe it is a flash tuner....no piggy back.
From a cost standpoint, the most cost effective option for a Stage I upgrad is the Dobeck Techlusiion TFI.
The Dobeck unit is a "pot" type fuel management system; think of it as an electronic carburetor. Unlike similar tuners like the V&H or Ness units which are throttle/rpm based, the Dobeck unit is load/speed density based. By comparison, the PCIII is throttle/rpm based and the SERT, SEST, TTS etc. are speed density based. Speed density is the better technology. Easy install, no dyno and the end user "tunes" by adding/pulling fuel. Open the link and check out the Gen 3.5 and Gen 4 systems. This system will also work with mild cams but if the performance upgrades include high lift cams, more compression and/or ported heads, you move into dyno territory.

Any other system is going to cost more but if cost is not a consideration, there are many more sophisticated systems to choose from. The TTS Mastertune is the current state of the art IMHO.

Fuel Moto offers their own EFI controller which is a PCIII. There is a library of maps, FM will program the controller for your build before sending it to you, dyno tuning is an option and the PCIII can be used to tune future upgrades like cams, heads, etc.

But I am leaning TTS down the road.
