Just wondering if the power commander makes a big difference in making the Z's power more linear and smooth especially in the lower rpm. I've just been noticing that my Z likes to bite a little bit in first gear when the throttle engages. I had a similar issue with the ZRX (although highly exaggerated in comparison) but that was because it was not properly tuned.

Regardless if a power commander will help I'll be needing to pick one up sooner or later because I'd like to own a K&N air filter in the future. Just wondering if anyone who has a power commander can confirm a difference in power delivery at low rpms?

Yes, you'll notice a nice difference with the map off of their site. I just had mine dyno tuned and it is electric smooth.

Wish mine bit right off the bottom. Mines downright sluggish. It's a little better with the new exhaust and I just picked up a pc3 so maybe I can tune the hit into the low end.

It's probably worth mentioning that I have an '08, so they are a bit smoother on the bottom, but flatter up top. I still think the PC III with a custom tune will do wonders.

I thought it would but wasn't sure if it was a big difference or not. Good to know.

It's nice if you have a switch to turn it off and on as you ride. I don't drive a car so I'm always in stop and go traffic with the 'bitey' bike.

I love mine, it takes the hesitation that was between 3-4k; and it smoothes it out some.

I had my 08 custom tuned on a dyno. Guys did an amazing job. Mine is super smooth throughout the entire RPM range. No hesitation anywhere, only vibes I get are close to redline, and they are very slight...

a power commander without a proper tune isn't gonna do much for you unfortentely. Yes you'll notice a change, but your flat spot may just move up or down the rpm range.

yes you can try multiple maps, yes you might feel a change but will it be perfect.. no.

So if your ready to fork out $300 for a smother ride on a PC3, be sure to allow another $300 for the tune.

(even if the tune comes further down the line)

my 2 bobs worth..

Same here. I look to change that as well. When I'm low it seems like the damn bikes carbureted!!!

Btw, does anyone have insight on how the PCV compares to the PCIII?

ps. if you think you bike is running that crap, then a service, injector cleaner and some new spark plugs will do a lot more than a PC3 will...

It just feels like the bike doesn't want to run smoothly below approx 3000 rpm. I have to feather the clutch to ride it smoothly otherwise it will lurch. It's not that bad, it's just a slight juggling act during bad stop and go traffic. I'm just a perfectionist and wanted an easy cheap fix. I wouldn't mind changing the plugs and whatnot but only if it will solve the issue.

+1 on servicing. and valve adjustment depending on mileage.
