I have a 21 mt07 it's been tuned for a year gets about 56 mpg and runs awesome. i decided to get the active tune and it started running like crap now mpg is 49 ,check engine light is on and it idles from 1100 to 1300 and back to 1100 like its surging. the power seems on but something is definitely not right.

the avtive tune says it's enabled and the flash was successful.


any ideas? I'm supposed to be riding it in the morning.
