RON 99

I've been driving with this tune for about a month now and it feels great. The only thing I'd say is that I sometimes feel as if the transmission is slipping and it doesn't find the next gear (this is just what it feels / sounds like, I'm not a mechanic). This happens when I'm accelerating through the gears from say 2nd/3rd to 6th. If I kick down in 6th then there isn't a problem.
