WORTH EVERY PENNY!!!!! LOL.....bet you thought it would be something else.....just got back from my ride...I have a akra ti and he loaded a akra carbon map....NEVER backfired/gurgled once I even tried to make it and it wouldn't, and before you say well the AIS was turned off, I had the graves plates installed with the pcv and got both....B mode I got reduced traction and its just as described a 400-600cc bike, you get on the gas hard and it goes though. Std I got smooth and that's exactly what it is...A I got quick turn and I am honestly going back to stock A but that's just my preference, nothing wrong with it but I just liked the stock A better...The cruise works and scared the hell out of me when I was testing all modes going through the gears, LOL....wasn't expecting it to latch and you know when it does.....Power wise I can roll on the gas in Std mode and wheelie before I couldn't without a lot more throttle, so something has to be going on.... The engine braking although not much gone I do miss, I could tell it wasnt there in my ride today but im only in the 5% of riders who liked it from my readings...Lastly this guy has answered all my questions in a FAST manner and to me this is the most important thing, so have no worries, I hope to get on the dyno this week if I can will post the results....SAFE RIDING EVERYONE!!!!
