So what exactly does a boosterplug do.. I looked at the website and what they claim. I've had the ECU replaced on my 2014 and have had no complaints. I am the second owner of the bike. I bought it with 11k on the clock and the first owner never replaced the ECU. He did put an akropovic exhaust on it. I have no complaints, but am not opposed to improving performance if it in no way compromises longevity. If there a reason I should get one. Would it make sense to sell the exhaust for a profit and go back to a stock one? Or should I do nothing? It's a bit rough below 2500 rpm but I twist a little harder in any gear and it fixes itself. Bike has never stalled in any gear except first when I newto it and had a hangover, total user error.... I have put 7k on it this year.
