Hello all,

I have an 08 XTR with Arrow cans, K&N filter and Iridium plug and was wandering is it advisable to use an O2 Controller on this setup. It runs fine as is with a bit of surging but not too much.

I'm heading on a 2500 mile trip this summer and mine has the smallet fuel tank of the group so was also thinking will this help MPG? Also does anyone have any tips for increasing the MPG on the XTR?

Thanks

The fuel economy improved by 5% on my XTZ after fitting an O2 controller if that's any help?

You can see the effects of the O2 controller in this post:

The whole thread's worth a read if you're thinking about fitting one:
