The ecu will learn about the mixture and auto correct. so for that and lots of other reasons I would avoid the Booster plug. If you really want to get rid of $200 then you can send it to me. Your bike will thank you. If you disconnect the battery for 20 min or so the ecu will start its Autolearning from fresh, ultimately wont make any difference but nicer for the first ride. still unsure about just blanking off the air intake to the SAS. getting the proper kit is fine but the UK customs are hot on putting crazy charges on anything coming into the country Last thing I bought from Italy had around 30% put on for customs, Tax and various charges.
