2011 Ultra Limited .Just got a head pipe cat gutted.Putting on supertrap stout pipes.Stock air cleaner.
Asked supertrap if I need a tuner.They said no as long as my o2 sensors are properly working.
Any one do this w/o a tuner

 

Take a trip over to niterider.com Some good reading on this issue there. If you do get a tuner, give Fuel Moto a call, they know their stuff on this.
Just my $.02

 

You don't NEED a tuner, but with the right tuner and someone who knows how to use it, you will get a little more perfomance and a cooler running motor.

As I understand it (and I am no mechanic) you can install free flowing pipes, OR, free flowing breather without a tuner, or chip remap. If breather AND pipes are upgraded then tuner or remap is required.

 

Heard that too.

 

Yup thats right.....no tuner required for what your doing, pretty much what I did and all I used was a VIED.

 

what is Vied

 

Any other advice.Dealer just told me 700 for a.tuner and dyno but thats ridiculous if not needed

 

No tuner needed, it will run just as LEAN as before.

 

I understand why things need to be adjusted with a breather and new exhaust, but can someone tell this newbie the difference between a tuner and remapping?
