Does anyone know of any tuners in Iowa? I'm in Cedar Rapids, I'm debating between just buying an AP in the spring or having someone do a pro-tune. Are the benefits of a pro-tune worth it over just getting an AP since I just have a CBE? I don't see myself adding many more performance parts, just want the car to run well. I would potentially add a DP if I went with a pro-tune. I was wondering if anyone had an average cost of a pro-tune, what I'd need (would I need an AP or just a tactrix cable?), and who is reliable around here. Thanks!
