    If anyone is interested, here are the results of the dyno runs performed on my bike last Saturday. A local shop was running a special on the PCV and installation/dyno runs so I decided to spring for it. I also opted for the Auto Tune module.

    The only mod to my bike is a LeoVince carbon fiber slip-on, otherwise all stock.

    Due to inclement weather, I'm not sure if this was totally worth the money or not as I haven't been able to ride much. The bike was already pretty smooth so there weren't any big dips in the fueling to even out. I did gain 3.7 hp which is nice, although I'm not sure how noticeable that will be. The chart doesn't show torque figures so I don't know if that improved or not. The bike was running a tad rich so this leaned it out a little bit.

    I think you'll notice a pretty big difference. You gained 3-5 horse from top to bottom!!

    Here's a shot of the install. The PCV and Auto Tune modules are pretty small.

    I'm surprised that Epic doesn't have the torque line on the same graph.

    The dyno software has another chart where it shows the HP graph across time instead of RPM. Seems a little more telling when you can say, "I develop full HP 2.5seconds sooner than before" as compared to "I have 3 more peak HP". As you mentioned, who can relate to what the later statement means in the seat of the pants?

    example here (didn't embed as to not pollute your thead)

    I would imagine that Eric should still have your data on file and might be able to provide similar if you called him up (provided you care).

    Thanks for sharing!

    Hey Tink, thanks so much for the info. It might be too late to get some different graphs from Epic but I might call to find out. Good stuff!

    right on man! Could be too late but generally they keep that stuff in the computer. That way if you make any further changes to your bike, they can compare to a baseline already on file. Just speaking in general - I've never done any tuning work with Epic. I have been eyeing that special he's running on PC and tuning for the 5th gen project I'm working on. Especially when he said I could buy in January and he'd honor the tune in the spring.

    Thanks for posting. Which Auto Tune did you install...the AT-200? Where did you install the O2 sensor? Working on mine now and am a little stumped.
