2010 fat bob, stock except for cycle shack slip ons. putting on a hypercharger. do i need to remap ?

 

You were OK with just the slipons, but when you put on a high flow intake you need some kind of fuel management. Lots of info and opinions here on that subject.

 

You can't "remap" without a fuel managment system. Don't bother with the factory ECM "flash", it doesn't do much and doesn't do what you need where you need it. If Stage I is as far as you plan to go for a while, look into the Dobeck TFI, either the Gen3 or Gen 4. DIY install and tuning, quality piece of hardware and great customer service.

IF you plain of doing more to it later you might wand a different tuner so when you do you are ready to remap.

 

if you have a warranty that you intend on keeping then i would go through harley for the remap
