However, I still think Evolve and Sal are also very solid tuners.. it was more a matter of personal preference.
FYI, it's your choice whether you want the rev limit changed, the speed governor changed, the cold start off and the 02 readiness on or off when you have them make the tune so I find it odd that you used it as a reason to use ESS instead when they can do the same things.
