Power Commander......Worth it?

Will i be able to tell much difference by putting a power commander on my Daytona 650 that already has a micron exhaust? Are there any other benefits to having a PC?

If you get a power commander, and then take it to a dyno shop where they will tune your bike to have a precisely calibrated air/fuel ratio across the entire rev range, the bike will be noticeably stronger across the entire rev band than it is now. No miracles, but stronger.

Don't think of it as adding power... think of it as extracting the power that you are not currently optimized to take advantage of.

Since dyno tuning can be expensive, you might want to consider doing an air filter and any other planned mods at the same time so that you can have the bike tuned with all the mods on it.

depends on if you have a full exhaust or a slip on. You won't see much of anything with a slip on since they are designed to work with the stock map. Full pretty much requires a PCIII because the ratio will be bad off.

Good point. I didn't notice if he said slipon or full.



If you just have a slipon, invest in a mid-pipe that eliminates the cat. Usually there is an independent fabricator who makes one for your bike. Will yield the same power gains as a full system in many cases, but is cheaper.

depends on the bike, i know a stock rc will see gains with a pc3, a slip on more and full the most, but its very detuned from factory

you dont have to get a dyno tune for a PCIII thats just silly... what you do is you buy the box plug it in to the factory harness and you download on the Dynojet site the new map... The map that you download is the modified map for the mods you have done for the bike.... so honestly dyno tuning your bike is a huge waste of time and money and will not yield any more ponies... From what I hear it wont necessarily make your bike run with a huge noticable gain but if you have a slip on it will smooth out the way your bike is running...

plus in some cases it allows your bike to shoot these cool flames.

I found the Dynojet maps to be super rich. Probably to cover their butts if guys blow their engines. Getting my bike dynotuned did make results but if I was doing it over,I'd have listened to M4 and stuck with the stock set-up.

Curtis that's a retarded and uneducated statement.

Dyno tuning is the ONLY way to precisely calibrate your bike. It's as simple as that. Every bike is different. Dyno tuning is worth the cash... or if you have a friend who has a dyno...

And like others said... the downloadable maps are not very good.

Whats bad about the downloadable maps is there on one bike of that make at the one altitude. And like said each bike is diff and we all live at diff altitudes. One could get by with the downloadable maps but it wouldnt be as smooth n responsive as gettin it dyno'd n tuned.

I'm going to agree with Mr. Boston on this one....

The map was made on a dyno run somewhere out west or down south.

for us guys in the N. east the maps don't account for elevation, humidity, or several other factors.

Man,I never get any credit! First ceo doesn't quote just says" as someone else posted" and then you give him credit. Hmrph! I say! Anyway,for a slip-on,and I checked with four exhaust companies,you don't need a power commander. Infact,it would/could be negative as the exhaust companies develope their slip-ons using the stock configurations and "tune" the pipe to the bike. The better companies log hours and hours on the dyno to get the best possible improvement using the the computer,etc. At least,that's how Mark over at M4 explained it to me (of course my dumbass didn't listen) and Yosh also said that no retuning was required with their slip-ons. I'm sure certain other guys on this forum know better than the actual exhaust manufacturers but here's my I have experience in this area (I've installed an aftermarket exhaust on EVERY one of the 14 motorcycles I have owned,not to mention dirt bikes and quads) I like it LOUD!

Yeah, the Dyno is the only true way to properly tune your bike.

Well I spoke with the owner of a motorcycle performance shop and all he said was you buy it and download the map... I asked him about dyno tuning he said there is no need for it... will dyno tunning squeeze out an aditional 1 or 2 ponies over the downloaded map... yeah probably but it really isnt anything you will notice so why pay the additional money for it...

but from what I heard filter, exhaust, and PCIII are not going to give huge gains... these bikes are so over-engineered they are already squeezing the most HP that they can do in their present state.... IF you want real gains your going to be looking at porting and polishing heads boring and stroking out cylinders and cams.... Or do what has been suggested to me GET A BIGGER BIKE (1000cc no replacement for displacement). But all that petty bolt on stuff really isnt going to do much for you...

Maybe not but the addition of a fitler slipon or even a full exhaust changes the curve and the downloaded maps dont always smooth it out where you need it.

Did said owner have a dyno? And you always have to remember opinions are like a$$holes even from professional shop owners

And as foar as displacement goes, my 600 will get across town just as fast as a 1k unless they run redlights :

Are you kidding? A full exhaust system, air filter, and PCIII correctly dyno tuned can increase max horsepower on my bike by 15-20%!!! That's a CHITLOAD.

Also... the tuning isn't all about ponies and max power. It's about calibrating the air/fuel ratio at ALL rpms. The max power may not go up more than one hp with a dyno tune, but the hp and torque curve will be optimized at EVERY rpm, and the smoothness of those two curves will be perfected. That's the point.

This stuff isn't about muscle and pure peak hp grunt. If you want that crap, go buy a vrod or a busa.

How do you know chris that the downloadable maps are junk.... have you ever used them... and how do you know that bolt on combo yeilds the 15-20% gain have you performed them and seen them on a dyno pull or felt the gain on your own bike... As far as I know you have a bone stock R6 what do you know about modifying bikes have you done it or looked into doing it... I know a little bit about BS parts that claim they add all this HP but dont as chit from moding my cars.... Trust me just because a company claims their product is going to ad power doesnt mean it does.
