Im a new 3rd gen wrx owner. I just ordered a v3 cobb tuner. I live in Arizona. As I understand it I can run (with no mods) the ACN91 stage 1 map with a decent degree of safety. As I understand it's more or less designed for stock setup. My questions are...
1.What kind of gains should I expect?
2.Is it a large difference with the ACN91 tunning map vs. the standard 91 map? Does anyone have any experience with this?
Thank you everyone
