Hardracing uses 13.5 AFRs on their WB2 autotune product which is way too lean (Dynojet's target was 13.2 for our bikes). Looking at KTM Performance's dyno charts posted on the RC390 forum, Chad's AFRs are around 12.9- 13.1 depending on the build. I've played with 12.6- 13.5 AFRs and it's a lot smoother down low and stronger in the midrange with an open air box running around 12.9. I'm very curious to see how your dyno run goes since your tuner is local to me : )

I went with hardracing because I couldn't swallow the $374 shipped from ktmperformance, that's just a bit much. I'm certainly going to mess with the maps, but for now it feels extremely smooth, making cornering a whole lot easier than before. Dyno tuning will be fun so I can actually see the changes instead of just going off the old butt dyno. I'm good with 13.5, as long as it isn't like the stock maps 14.5-15!
