I have a 01' with a full micron system and PC3 USB. I am going back for another dyno tune(250 load control dyno jet). I need a new filter and thought might as well get BMC race filter since it's getting remapped. Do you guys think any noticable gain will be possible. Bike made 161 hp & 99 ft.lbs. I am going back to same dyno. Thanks for your input

I put on an BMC street and noticed a sharper throttle response and it seemed to pull a little harder up top. The race version flows a little better but doesn't filter as well.
 
I run about the same setup you have. I run the race. It has 4 layers of filtering material. The street version has 6 layers.
 
i have a bmc race, the bike needs remapping if you use it. you can see right through the filter, it flows!
 
I use the BMC Race also, but never ran the stck filter so i can't tell ya if there was a difference. All teh mods we're done to my bike before it was ever riden. I did the break in with all mods done till 500-600 miles, then i Dyno'd it.
 
I am remapping because of lean surge at smaller throttle opening. The p.c. was mapped perfect, but I had different gas in the bike(no ethanol/reformulated b.s.). When I refueled in my area, the bike did not run the same. In the chicago area gasoline is reformulated with up to 10% ethanol. Lesson learned. I will trailer my bike(with gas I normally run) to get remapped this time.
 
Good point dave. I have even seen some differences in gas from station to station while monitoring the A/F on my bike. Not major but a difference I can see in the logs.

I recently installed this filter and that was my seat-of-the-pants impression.
