Power delivery is pretty smooth. Builds nicely right off idle all the way to redline. There is a bit of a stumble from closed throttle to open...an aftermarket pipe smooths it out a bit. ECMspy gets rid of it completely. The XB9's aren't as wheelie prone as the 12's...and even then it's not like keeping the front down is a chore. It will stay down...but if you want it to go north it will.
