just bought my beautiful K&N RK-3909 today. man that looks sharp. Now for the power commander. and ofcourse the correct map.

 

805-510 is the model number of the actual power commander. 805-511 or 814-511 is the model number of the kit that may include a bracket for a specific bike / zip ties / 9v adapter, etc.

if i run this without the power commander what will happen? more popping and run shitty?

 

You will most likely be running leaner than stock which is already a little lean. Find you a map from the dynojet website and try it out.

Deppends how you ride it. The closed loop sections would most likely tune back to a 14.7:1 ratio. And the open loop sections would change due to changes in the rest of the map but is a gamble where it is in the AFR. If the system can't get it into range in the closed loop sections you will see a check engine light and a code for the O2 sensors.
It is recomended to have a reflash or a aftermarket fuel management system when swapping to a free flowing exhaust and airfilter. Changing just the exhaust I found the delphi system able to tune just fine on it's own. I haven't tried with a exhaust and air filter swap.

 

I installed the filter. It deffinatly has more power. Sounds real nice. Cant wait to power command it. There is no popping on the deceleration what so ever. I think its great.

It took about 1/2 hour to install. i have a few pieces of left over crap. a few screws, the old filter and casing.
