Do you know what sort of mpg you are currently getting?
I have a 14 wr450, FMF
Q4 slip-on, stock header, comp ecu w/short throttle screw. I also have the tuner, never ran the comp ecu at the shipped settings, but have tried many of the maps listed here.
On average, with the above mods, I get 70-90 miles per tank of fuel, depending on the map
, and my throttle usage. Coming from an old kx250 2 stroke, am just giddy about my range now. If I do ever need more range per tank, I'll upgrade to one of the after market tanks.
I ride northern MN and some parts of MO, average running 3-4 gear, woods and some gravel roads. One of the maps I use is for slick mud and it really down grades the motor, falls really flat on the top end, and also gives me the best mpg. It's great for tight technical and let's me lug with out stalling out.
I would look really hard at the tuner that allows you to program in different maps.
My stock ecu WILL NEVER be put back in my bike. Just way to lean and just gives me the feeling the motor is crying out for help.
Btw, I have not adjusted the CO yet with the dealer programmer, but it's on the short list of items to take care of. Mine starts ok, hot or cold, but I do get the glowing header with a little idle time.
Lots of great posts on here regarding maps and dealer setting of the CO.
Congrats on the bike, I absolutely love mine and a best friend sold his DRZ400 after riding the WR. He couldn't have one soon enough.
