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.
 
Dyno Testing with a Sidewinder--baffle in or baffle Out?
 
I have a street megaphone on a Hayabusa with small box mod, stock filter, PC3USB, 87 pump gas? I have a flat spot with hesitation from 2500 to about 3300. Which map do you recommend for it? Don't want it to run too lean.
 
I've been using the map that was sent to me and I checked my plugs and it appears that I'm running on the lean side of things. There's some detonation going on and it's causing the plugs to loosen. I'm running 93 octane pump, should I switch to 100 octane?
 
I just installed a Two Brothers full system on a ZX12R, it still has stock air cleaners, should I get after market air cleaners for full benefit? Do you have any recommended maps?
 
I just put my ZX-14 back together. The head is ported by Spaz and I degreed the cams. Also has JE 13.5:1 pistons and Carrillo rods. Smeg, flies out, BMC race filter. I put the SS map you sent me in and used 93 pump gas. It starts and idles great but I tried to take it for a ride and it was bogging and dying on me bad. I thought it was too rich, but pulled a plug and it was very clean, looks lean?! I am just trying to convince myself there's nothing wrong with it and it just needs mapped. Is there anything else that could be causing this that I can check.
 
What is the best octane for the best fuel MPG? Do you have suggestions to improve my fuel mileage?
 
Why does my bike get less gas mileage after I installed your exhaust system? Primary use is street, but stoplight drags are frequent. Only the exhaust with O2 plug was added to the bike.
 
How much race fuel (MR12) should I run? How do I clean the fuel system after the race?
 
I currently have a map from you in use. The only concern I have is that when I am using my air shifter which is 99% of the time that it back fires and shoots about a foot long blue flame from my exhaust. Am I running rich or lean?
