I have a question to which i have not had a defining answer yet. i did stage one at sturgis at the V&H trailer, power headers, AC mod and fuel pack. it seems to run okay, but a friend had pipes and SE breather out on at a dealer and they did a down load and his seems to pull harder than mine. both are 2012 streetglides 103CID.
MY question is this...will it make a big difference if i take the fuel pack off and have dealer do download, & what exactly is the download and what does it do? would it be better to go with a power commander?
I am not looking for a drag bike but some more torque and hp is always good. BTW my friend gets about 4 miles per gallon better than i do as well.
Hopefully some dyno techs will chime in with some specifics to help my decision?
thanks in advance...
