Hey guys. Just picked up my 2014 ZX10 about a month ago. I currently have a Bazzaz ZFI, M4 street slayer slip on, and am sending out my ECU to Archer next Monday for him to do the aggressive flash to it. It won't hurt to run both, will it? After I get the new ECU installed I plan on having it tuned again. Also, Shouldn't a shop always tune a bike to the AFR? A local shop in Evansville Indiana told me that they just tune the bike to what the computer gives out. Does that seem legit?
