    High. So I'm doing some mods to my SMR511 for the winter season. It's getting snow tracked so I removed the air box and made a simple wire frame to hold a prefilter. The bike has a PCV with auto tune and was running perfect with the factory air box and a wr450 pipe on it. Now with air box removed it idles very high unless I crank down air screw to about 1.5 turns out, and it seems flat response off idle. Not surprising since it must have a lot less vacuum now.

    So, I'm no tuning guru, although I've done some stuff in the dynojet software to get it running well.

    Should I just let the auto tune build me a new map or should I do some adjusting now?
