Dyno tuning results! good results, but still a mixed bag...
The top line is with the muffler completely removed... I had no idea that the Burns muffler was that restrictive... I'm a bit surprised... I may end up just running a straight pipe as a result of this
BIG THANKS TO TIM AT XACT DYNO! I'll be going back there again once UpRev increments the software to include valve and cam adjustments
