I just received and installed (quite easy) a power commander v from fuel motto......and what a difference. I know I could have went with more progressive tuners but I have no intentions of going past stage 1. My FLSTFB has a SE a/c (K&N) and V7H 2-2 big radius pipes. It had no low end throttle and sounded like a full auto with the decel pop. I live in PA so it was a cool 33 deg. when I got out and it pulled and purred the whole hour I was out and probably still wouldn't be home if I didn't have other **** to do. I am one happy camper..thanks FUEL MOTO for pointing me in the right direction and only selling me the best option for me..:icon_b anana:
