RE: Help w/diagnosisbad MPG
Kansas, what is your final recipe? \\; Are you running any fuel management or an ECU re-map? \\; Curious, as I have an 07 with SE Streets, A/C and XIEDs or IEDs (I am still trying to find the right setup).

RE: Help w/diagnosisbad MPG
Think the original owner mentioned that the dealer did a map for SE stage 1 and Rinehart pipes. \\; I'm running those with stock fuel management. \\; If I ever get to sea level or lower than 6500 feet altitude I may be lean and will pursue a fuel management solution then. \\; Right now it runs great and the plugs look outstanding.

If you had a Stage I remap done on the bike, the race tuner was not necessary, at all.
I would suggest installing the IEXDs for the closed loop lean condition you will still be experiencing, because the remap only affects the open loop operation of your bike. In my opinion 53 mpg is too good of fuel mileage and indicates you are running too lean, now. The IEXDs will allow your engine to run cooler, but will probably bring your fuel mileage down into the upper 40 mpg range.
I would also vote for the K&\\;N filter, when you have a few extra bucks. You will improve the airflow an enjoy a little more performance, also.
Watch you pipes near the exhaust ports to see if they are glowing cherry red or not. If so your engine is difinitely running too lean.

RE: Help w/diagnosisbad MPG
Ok, So I get crappy milage too...
I get about -30 city and like 33 highway.
I got crappy milage since i bought it when it was stock btw.
 \\;
Part that pisses me off, is I got thundermax....
Got the latest firmware, and the correct map.
I rarely get decel poping (07 sb, thundermax, big sucker, rush slipons)
 \\;
So I should check/replace my plugs first right....

I'd check your plugs...that's what sealed it for me. \\; Once I got the mixture right now it's no black on the threads and light golden brown on the white inner piece. \\; No glowing on the pipes. \\; No excessive heat on the engine, although there is more now. \\; No pops on decel, no starving fuel engine symptoms.  \\;
