Let me see if I have this straight.
If you are cheap- Remove Butterflies (free) = better “Performance”If you are cheap but have the skill and time- Remove Butterflies (free) = better Performance/response + partial traction control negative effect.
If you are not so cheap- Guhl’s Reflash ($400) = better “Performance” + 1HP + TorqueIf you are not so cheap and/or don't have the skill and/or time- Guhl’s Reflash ($400) = better Performance/response + 1HP + Torque + no zero effect on traction control + some adjustability (reflash).
If you are not cheap at all: Power Commander($400), ZX-14 throttle bodies ($200 ebay), areaP full ($1000) = Best “Performance” +/- 30hp (160hp range) + Lots more Torque.If you are not cheap at all and have lots of skill and/or time: Power Commander($400), ZX-14 throttle bodies ($200 ebay), areaP full ($1000), new headers ($!!!!!), and remove butterflies = Best “Performance” +/- 30hp (160hp range) + Lots more Torque + full adjustability + expandability + partial traction control negative effect.

I did the full Area P with flies out, the PCV and had it Dyno tuned.
Don't under estimate the importance of doing the Dyno tune with the PCV. It made a big difference in drivability in the low to mid range. My bike had some stumbles in a couple places in the power band and the tuner was able to clean all that up.
It did bring it up to 157hp, but I liked the improvement in torque especially at 102lbft.

So if I were to buy a PC, remove the flies, and just run my Cheapo Delkevic can, would I at least get to 150hp?
I just did the Guhl reflash and to me, it's like a whole new bike. I have spun the tire several times. I am pretty heavy handed with the throttle, that's what I bought it for. I tend to change rear tires frequently. I have newer Angel GT's and freaking love this mod. It seems to have added power everywhere. Just touch the throttle and it leaps.
Might have missed it but I saw nothing in the ad about headers and midpipe which to me is a full system.
SO stock bike, Guhl reflash only? No exhaust, no PC, no flie removal? How has your Mileage faired?
BUMP!! Do I need to remove the Flies on my 2010 or not?
Thanks Maxtog! I think I will just have them disabled with a Guhl reflash. Anymore than that is more than I personally care to tinker with. I just had the bike apart today, and was wondering if I need to do it.
