Ive read a bit about TuneECU, I have a mate thats really into all that stuff. Hes forever mucking about with it. A little tweak hear, a small adjustment there.
The honest truth is I couldnt be bothered with it. Computers leads, and the possibility of being a total numpty and mucking my bike up, put me off.
I know the booster plug works for me, so Im happy to plug one in and forget all about it.
