Hi all...What kind of horse power should i expect from my Fatboy lo fitted with some decent slipons,Hiflo inlet and tts mastertuner.Im thinking its going to cost me around $2k minimum.Where would i expect to see the power gains mostly?

Reckon you'd get HP in the low to mid 70's and torque in the low to mid 80's...................just roughly!.........depends a lot on your tune!

Burto.

Hi all...Thanks guys.Where would i expect to feel the incease in HP and Torque in the rev range???

well can't tell you how many horses, but  thought i'd say i was watching an EFI harley tunned on a dyno jet 250i, the other day. they used a SE race tunner. then they used one of the late model power commanders, the power commander they used had its own controler, you could carry in pocket or have mounted on the bars. the race tunner costs about $700. but needs a lap top, and can not turn off falt codes.

this power commander costs $500 and don't need a lap top to change maps plus it can read falt codes & turn them off. BUT you still need a good tunner to custom you some maps. no one tune can give you everything its always a compromise so having a power map that gives you all melbourne cup winners feed up on oats, for maxium thrill ( but how much do they cost? )

then you got another map that has all Clidsdales that can pull stumps out and just eat charf for when your touring.

then another map with shettland ponys that eat grass, for around town heavy traffic.

now with this new Power Commander you can have those three tunes ( if you know a good tunner, or use a recomended power commander tune center ) you can change these maps easy with out a lap top.

i've got a carb twin cam but if i buy a new EFI model thats what i'll get.

cheers
