Where's the fire? Sheesh man, slow down. Two misspellings in a four word title? That little red dotted line under the word means something is not quite right.
If you arent doing anything other than an air cleaner upgrade and exhaust then there really is no need for a tuner.....Harley will tell you otherwise b/c they are under the watchful eye of the EPA
So does that tuner thing mean nothing if all you plan on doing are exhaust (V&H Big Radus) and high flow air cleaner the stock system will compensate enough on an 07 Nightrain.
I would run a tuner helps run cooler and better. You can go with a PC, SERT, TTS, T-Max auto tune, V&H fuel pac, I went with a SERT at this point, had XIEDS and they work real good too. JMO
best tuner for nighttrain
