Holy smokes... This thing sounds like a freakin monster..hahaha
Some decel popping at 3000k-4000k rpm downshifting. Two minor backfires (I guess..wasn't like a car one) while riding for 1 Hour. Aside from that, acceleration was smooth and consistent. Hard acceleration was sharp and responsive. No slop.
You hear it in your helmet around town. It quiets down above 50.
I like it (I'll still install JB though) just to have in place for future mods and optimization.
Install it now! That machine will run 10 times better just set to map 3 with the pipe. I guarantee it! Heck, I run mine on map 1 with the factory pipe and filter sometimes and It runs amazing (Exponentially better than without the JB). You will notice a huge improvement instantly so go ahead and install it now and set it to map 3. Verify it by installing the software on a laptop and plugging it in.
