Hey All, and thanks for the help.

I have a SE Heavy Breather and V&H slip-ons. Already had a dyno tune with a SE Racing Tuner.

Bought the bike in Cali, and I don't want the catalytic converter anymore. Want to get new V&H headers. Catalytic is making it super hot on the back of the legs and for the passenger.

So, recommendations on whether I need to get another tune? I assume I'm opening up the air a bit more on the back end, but is it necessary to get another tune, especially since I had a SERT dyno with the SE Heavy Breather?

Thanks for the help!

Yes, changing headers is a bigger impact to how your motor will run than what you've done so far.

 

If you are going to have to dyno it again you might as well go ahead and put in new cams then have it dyno'ed. You will be much happier in the long run.
