[GMR-PERFORMANCE]

This is one of the bike's we built a few months ago. Customer wanted to install the CFR mufflers and a SE 58 t/b . So graph has his other build with the Crusher mufflers vs the CFR.. Down low ( where he does not ride) he lost tq however we did pick up gains mid and upper.. With more time it would have been great to test the CFR vs crusher then add the T/B but. Customer is from Tulsa so time frame was an issue.  Customer is happy with the sound and look of the muffler and the increase in power in his riding range. IT may not be for everyone but for this guy it works. And that is what counts.   The tune with the TTS was not bad but I did have to make the map huge on CI and drop inj to get enough room MT9 cal with EGR made the tune much better than the pro tuner. VE's are much smoother down low than with the other tuner.

Personally I think I could live with the lower numbers for the smoother curves. Great work with what you had time to do.

I'm with OBB, I'll take the Crusher curve, all day. I do think you did as well as can be expected with the CFR's, fine work.
