Thanks to diablosport

Ive been reading a lot about people saying that that the tuner doesn't do anything etc.
I would just like to say that i ran a 5.5sec 0-100km run with out custom Johan tune on.
Then immediately uploaded custom tune and re ran on same pavement, same conditions and ran a 5.2sec 0-100km.
Also I may have begun to let off as I was eating up pavement and gaining on traffic.[in mexico ]
conclusion: diablo tuner and solid custom tune equals 3 tenths in a 0-100km test possibly more.
Thanks diablo and datoona.
