I replaced the K&N air filter with the stock air filter and ran redline fuel injector cleaner thru the system. New result is 157.87 hp @ 92.61 ft/lbs. (higher ambient temp /lower humidity) When I changed the filter, the idle dropped, and I had to adjust the idle up to keep it running. I would think this is more restriction? The dyno shows the bike is now running richer than with the K&N filter, but producing more power?? People have suggested dyno tuning the bike, I wanted to get yor input before doing this.
 
How can Brock's get mapping so close?
 
I have removed the secondary butterflies on my GSXR 1000, will this affect the map for NOS and MRX01? Also, if I wanted to run pump gas most of the time and MRX01 in grudge matches would the map need changing or should I get it dyno tuned to be on the safe side anyway?
 
Dyno Testing with a Sidewinder--baffle in or baffle Out?
 
The speedohealer for my 08 Hayabusa didn’t work around the stock speed limiter. The product is installed and working properly as far as I can tell. I can program in different % offsets and the speedo reacts like it should, but the bike ran 180MPH in 6th gear on the dyno and signed off.
 
I have an 05' Hayabusa with Brocks Air Lid and P.A.I.R. block offs. When I installed the block offs the bike would not stay running at idle and seemed to run rough. I purchased the Power Commander III and hoped this would solve my problem. Unfortunately no one seems to have a map for a bike with the PAIR valve removed. What am I supposed to do? I was trying to avoid taking the bike somewhere to have it dyno tuned but if I cant find a map this is my only option.
 
I'm degreeing in two intake cams on my Busa and I would like to know what lobe centers to put them on. The motor is fairly stock with a Yosh header, 4-2-1 style with an exteneded arm, set up for 4 gears in a 1/4 mile and I weigh 220. Also, it has a Dyno Jet Power Commander and has been dyno tuned 159 H.P.
 
What causes my stock 2007 Hayabusa to burn oil when warm, especially on deceleration? It still dynos a smoky 171 hp.
 
If your Street Meg & Gen 3 pipe both share the same exact front header pipe, how is it that the Smeg, I am being told is able to produce more horsepower then the Gen 3? A friend of mine has one of your pipes and got a motorcycle shop to install it along with a power commander. The shop didn't use the map Brock's had supplied and said they preferred to custom map the bike. What is the advantage or disadvantage, if any of doing it this way over using the mapping you supply?
 
I've followed your progress on the 2012 ZX-14R. The ECU mod put up great numbers, so why use a Power Commander? The ECU mod removed the top speed limiter and still provides a great a/f ratio from the Dyno sheets I have seen.
