So I've got nearly 1700 miles on the base tune and F23 now. The car still makes me smile and I've driven it more in the last few weeks than I have since we bought the Volvo (family car) last year. I can happily report that my "sports car" is finally faster than my SUV family hauler. If you want to go out and beat it the tune is great, driving around town isn't really a problem at all either. In fact my wife didn't even notice a difference when she drove it. However with extended seat time and running it through all the paces there are a couple of "gotchas" with the tune. It will stutter a bit when you do a partial throttle acceleration, say switching lanes to go around a car, You don't really want to squeal the tires but you don't want to disrupt the flow of traffic in the other lane so with moderate pedal modulation you zoom away after a short period of lag and what are we doing race car or driving miss daisy decision the car leans toward race car... It will drive miss daisy no problem but there are some hiccups between the two. Its a very streetable tune, and I'm not knocking it at all just sharing my thoughts and experiences. I plan on getting a DSG tune and a proper dyno tune as soon as I can now that I feel I've give this tune a comprehensive test. We'll have the Volvo back early next week and we won't be putting many miles on the GTI for a while again.
