Good choice. I have run the full stainless on my R6 for the last year and it has been perfect in every aspect.
Keep me informed on how it goes and send me a picture for our gallery when you get a chance. Thanks, taige

Is that with a downloaded map or a full custom tune?

A downloaded map is a full custom "Fuel" tune. Do you mean , degreed cam sprockets, compression lift, etc. (no extra tuning like thatwas done)

These results were from a stock OE motorcycle with exhaust and PCV.
Hope this help. If you have any further questions let me know. Taige

I guess what I was asking is, was that PCV map tuned on that specific bike? Reason I'm asking, is there are some local guys to me that have a dyno. After tuning a PCV on the dyno, they are seeing a few more HP than some of the maps that were downloaded. I don't have much experience on this subject, so thats why I'm asking. Thanks.

All dyno's give different answers due too many variables.

There are so many variables that come into play regarding dyno results.
The dyno, the tuner, the room, the temperature, the humidity, the bike, mileage.....you get the point. Some of the things to look for accurate comparisons are-

(1) Back to back test comparative test. Dyno the bike with the stock exhaust then, in the same room on the same dyno, with the same motorcycle, do a run with the aftermarket exhaust. This should show accurate gains between the runs. It is very difficult to have one bike dyno test run on one dyno, in one room, with one tuner and then 2 weeks later take the bike to a different dyno, different location, with a different tuner and expect a similar result. Now a custom tune definitely has potential to produce more horsepower than one of our download maps because again you are tuning to a specific set of circumstances which is always better.

(2) Avoid the need for a fully custom map. One concept that has recently taken fuel management to another level is the Dynojet Auto Tune. This is one of Chuck Graves favorite new toys for his 2009 R1.
This is a separate device about the size of a large pack of juicy fruit gum.
It has its own oxygen sensor that you install into the O2 location we offer in every Graves Exhaust system (except the slip ons in which you to retain your stock O2 location). This sensor sends air/fuel measurements back to the PC so that it may adjust accordingly. This is like having your own dyno everywhere you go and a custom map at every turn. TRICK !!!
This also allows you to switch between ecomomic and race maps, it will adjust when elevation change occurs, it will base its middle point off of your downloaded map and then adjust 20% up or down to retain correct A/R. This will not only give optimum power but you will get better relative fuel mileage.
There is a lot of great features with the PCV and Auto tune. We will have a complete web page describing this in full on our website by the end of the day.

Thanks, taige

I understand all the variables when comparing dyno numbers. They start off with the bike running very well off of a map for that bike, and then tune from there. It's always the same dyno, same tuner, I don't know if its the same day/temp, etc, thats going to depend on everyone's schedules. But thanks for the info. I can't wait to gather parts and the PCV w/ autotune, that sounds perfect!

The header design can defintely add some significant performance in all the right areas but unfortunately you cannot fit headers up to the cat eliminator system. the sizing and connection points are different. You would have to sell the CE and get a full. It is worth it if power is your main consideration. Thanks, taige

Here are my thoughts on Dynojet vs. Bazzaz.....
Both companies build a quality product....both companies have great engineers and good technology....... however there is one items that puts Dynojet up on top. It is the industry standard. The parts, service, dynamometers, fuel maps.....basically anything you need or want from them is extremely easy to acquire. With one phone call, email or trip to an authorized dealer and you can immediately fix any problems or tune for power.
It has been tested and tested for years on the street and everybody knows Dynojet. With all of this testing, come reliability. They have spent years and "working out the bugs". Bazzaz has been around for a while however when you talk about Dynojet you are talking about tens of thousands of riders using the product over the coarse of years and years. They are very connected to the street rider and racer alike. Not saying these are reasons to choose one item over the other however they are important.
Ask yourself 3 questions.
What is most important to you in choosing a fuel management system?
If you just want a reliable unit that will allow you to remap the bike easily go Dyanojet.
If you are looking for maybe some additional features like traction control then go with Bazzaz.
What are you using it for?
If you are running around on the street ....at this point I would suggest the DJ unit simply for the fact that it is proven very reliable and almost every decent mechanic knows how to work with Dynojet products.
If you are racing the bike and then both companies will get the job done, It is a matter of what are you and your mechanic use to working with ?
What level of skills do you have?
I would estimate that 9 out of 10 tuner shops know how to use Dynojet products, in fact a majority of them probably have the DJ dynos in house. Bazzaz is growing but you will not have as many tuners familiar with that product. If you are low on the level of mechanical skills and you just want to
download a map and install the unit onto the bike.....and not have to think about it for a long time. Just ride.....I would push you toward the Dynojet.

Either way.... like I said both companies build and design quality product....however just for the fact of it's proven reliability, household name in tuning, and the easy to use components I would edge toward Dynojet. Thats what I have run on my R6 and it has had 0 problems. I feel confident about going out for long rides and if anything breaks it probably will not be my Power Commander. (2 knocks on the wood of my desk).
I am still working with a PC111 but very soon I want to move to a PCV....I have been learning about it and hearing that it is really advance incomparison to the PC111. Thanks, taige

Thats my belief for now. Thanks, taige
