Thanks guys. Yeah I know that openecu is risky if you don't know what you're doing. I think I will get that stage 1 map, and study the differences and such before I change anything, if I even change anything.
Edit: I'd rather have this one. I got it for a steal, +1, 2.5 liters, +1, and low mileage +2, no mods +1. I'd rather spend the extra 7 grand for pretty much a brand new car.
