I have a '07 Tiger that had a Two Bros slip-on muffler and map 20164 (= TOR with cat+SAI). I used to get over 40mpg, typically ~43mpg
I then removed the following: cat, SAI, and snorkel. I loaded 20166 and reset the TPS. Bike runs great, noticable power gain and less on/off snatching. However my mileage is now down to less than 35mpg.
Have any of you experienced such a large loss in mileage?
I am consider using the latest Arrow race map without SAI = # 20546.
Actually the bike was pretty good after removing cat, SAI, and snorkle with 20164 other than it threw an error for SAI circuit being open. I measured the resistance of the SAI solenoid at 20ohms. I could put 20164 back in and a resistor in place of the SAI solenoid
