Hello All-Great ridin weather I hope for you all!I'm wanting to get my baby Dyno Tuned-I've got flies out,and a PCIIIusb.Stock pipes.The installed map from Dynojet works fine I guess(?).My baby runs very good right now.Any thoughts on increased performance with a Dyno Tune? Would it be worth it?Thanks all-Ride safe there-Have FUN!!!!And be careful!(no plans yet on changing pipes).(PCIII installed in March of 07).

I have the same mods(performance wise) and was looking at getting it dyno tuned too, not sure if I'm gonna get some pipes or not, I kinda like it being really quiet.

If the current map is 'off' a little/very close, you may only get 3-5 HP out of a tune, for $$$. If its off a lot, say 5HP and higher than before your changes, you'd probably feel it, sluggish and all.

It its pretty snappy, you are likely very close.

Unless you have any flat spots I think JDC is right "on the money"

I'm pretty heavily modified. and going from the stock tuning to a dyno tune i only gained 10 hp.

I'll restate my observations on dyno tuning, I posted a good read on this subject from Dan Kyle Racing.

1. In the end, a custom dyno tune is only as good as the tuner. Find one with lots of experience that comes well
recommended.

2. A custom tune is only the starting point and not the end. You do not ride a dyno and you do not ride at 100%
load all the time. You may have to adjust the map to make the part throttle driveability good.

3. The tune that makes the most impressive numbers on the dyno chart may not be the most fun to ride or even the
fastest out on the real road.

4. If you have a map that works, don't mess with it!

5. I like the idea of taking an existing map developed for your setup (pipe, airfilter, other mods) from an expert
tuner such as Brock's, DynoJet, Ivan etc. and then tweeking it to get what you want. These guys spend a lot
dyno time and out on the road/track time getting it right so it should be very close, only small adjustments to
compensate for altitude, temperature differences.

Thanks all for the comments-Probably just leave it alone then-She does run good.I did notice however that my fuel mileage dropped from 37.7 to 37.1 just recently-any thoughts on that?I can't think of anything I'm doing different.Ride safe all!!!(it stayed at 37.7 virtually all the time,now at 37.1 all the time).

blue07 I'm showing about 34 mpg but with a powercommander in series your actual mileage is most likely a lot less. Mine was an actual meaured 28 mpg last time I checked so your fuel computer is off by about 6 mpg give or take. Main thing is how she feels. Mine pulls hard from just off idle to redline with no flatspots so I can accept the low fuel mileage. For comparison, my bone stock '07 CBR 1000 gets 30 mpg ridden the same way...hard.....so maybe not too bad.

Thanks Kruz-Ya,I can accept 37 something(or as you said).Just thought it was strange that one day it would be where I said,then the next day have such a difference.She runs great-no complaints here!!!

Yep I agree with Kruz for sure big numbers don't always mean a faster bike on the street. It hard for a tuner to tell a customer that just spent 300 plus dollars on a custom tune that he only found a few more HP if any at all. I bet most people don’t give a damn about perfect A/F ratios they want to see big numbers. I ride a buddies 07 with a full muzzy system,TRE,and a custom tune all the time. That bike supposedly made 182 hp on a dynojet 250i. My 06 with no flies, Yoshi slip ons and a generic map provided by HPC will stomp a hole in his AZZ from any gear below 8500 rpm. Yes his bikes feels a little faster from 8500 but who spends time above 8500 rpm besides someone racing. I know my bike is not making anywhere near 180 hp but if his is mine is too. LOL . IMOP slip ons, no flies, with a decent map is a great combo and the best bang for the buck.

Area under the torque curve says it all when it comes to rideability, give me a smaller peak number but a fat midrange and bottom end any day on the street. Look at the older R1's, almost always post high dyno numbers but at a bazillion rpm with relatively gutless midrange. Works Ok on a fast track but catch a tight track with lots of corners and the bike is a handful to keep moving. That's the problem with the 08/09 ZX-10 I hear, not enough spread of power for the street, too track focused. Who wants to ride everywhere at redline?

I'd guess your MPG dropped for 2 reasons, you installed a new toy and you've probably been out "testing" it, harder/more aggresive riding will kill fuel economy. If the power commander with the new map makes "more power" the power needs to come from somewhere, so chances are you are burning more fuel.
