I used to have a 2008 Dyna Lowrider and installed the Vance & Hines FuelPak. It worked as advertised, nothing fancy. The engine ran a bit cooler, minimal backfires on deceleration.
Now I have a 2012 Street Glide and installed the Dynojet PowerVision with a map from Jamie. Different ballgame altogether. The bike runs flawless.
revolution performance ems, bike runs actually perfect
I agree-- I run the EMS on my 09 UC with Stage 1 and cams and couldn't be happier.
I removed the dealer installed SEPST due to decel pop.
The EMS cleared it up on the 1st ride, and I can change engine parameters (different cams, headwork, etc) with no re-tuning. True plug and play tuning.
