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.
 
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?
 
Can I use Brock's maps with fuels in different countries?
 
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.
 
After my ride today I noticed that the end of my exhaust pipe was wet with a very watery substance. Normally it is dry more like soot. I was wondering what could this be caused by?
 
I notice a huge difference in the Pump Gas Track map fuel added at 100% throttle starting at around 7k rpm's compared to the other maps. Is this correct?
 
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.
 
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?
 
I put my ZX-14 on the Dyno yesterday and made 189hp and 113 for TQ with your Smeg and track map... It starts to run super rich between 4200 and 5000rpms and dips down to 11:1 AFR. Will this change with the bike moving and ram air working?
A/F ratio question 
I have one of your track maps in my bike and I think the bike is running a little rich. I have a wideband and I was wondering what air fuel ratio I should try to achieve?
