Thinking about putting reaper cams in my 07 NT with stock 96 ci. Currently have the daytona twin tec ECU and was wondering how would I go about tuning it as far as base map goes.

 

I assume it's the M8FI Gen 8 System. Check out their Software Download tools.

 

I have a Gen III Daytona Twin Tec on an 03 Road King . Most of the tuning changes I've had to make with new builds has been timing changes - pull some out in the 2K - 3-3500 RPM range under acceleration - use the MAP readings for this - on mine it's when they increase from about 16 - 18 . You can modify your current tune , or start with one of their tunes that most closely matches your build
