im thinkin of ordering the stage one kit, and i was wondering if i needed a fuel pack. i have the screamin eagle street pefromance slip ons.

 

You will certainly need something. Fuel pack is one option. Tmax or the HD remapping are also options. I went with the Tmax with the idea that I will not need future maps and save $$$ that way. Love the Tmax, got it on the forum from Shooter64 (Cateye Customs)
