No he just does OpenSource tunes. When he does my car. I think I am just going to unmarry my AP from the car and sell it and stay with the opensource.
At first I was kind of skeptical of opensource tunes then I started doing a lot of reading on them and found that they are just as good if not better than using an Cobb unit.
The only downside you really have to find someone that knows what they are doing even more so than a tuner using the Pro software from Cobb.
Also, you don't have a nice handheld unit to save tons of diffrent maps to. You have to save them to your laptop. No big deal for me I just am going to run one map and that is it.
