Not sure if I read on this board or the other boards I have been on but has anyone switched from Justins Map to Evolution Performance map ? I would like to know the difference if any. The reason I ask is Evolution is only 185 miles away from my house and thinking about going up to have some work done. Talking with Fred they want me to use his map since they are going to be doing my work. My car runs great with Justin no complaints at all, but if I change injectors, pulley whatever I will need a new tune. Since I am right there it makes since to have it tuned by them. So anyhow back to my question just wanted to see if anyone switched and if so did they truly see a difference.
Thanks,
