So I had my tune installed last week and have only had a chance to drive my car a few times since but my immediate reaction was that it felt the exact same or even a little bit slower. All the posts I've read about tunes on here it sounds like it made a big difference and im wondering why I haven't felt it. Also I thought the tune changed the tach limiter to 6500 from 6200 and my car seems to still be shifting at 6200. Im debating on going back to stock and then trying to download the tune again to see if it makes a difference. Any other suggestions?
