For me the DSG tune made my car better as it wouldn't down shift unless I was flooring it and even then it took some time to down shift. Also going to a stop pretune would shift to 1st way early and cause high rpm, after it stay in 2nd even at low speed for a smoother ride.Finally got the Kerma engine tune put in. So far (60 miles) so good. Seeing a ~ 5-6% jump in fuel economy. Also, so far seeing no need for a DSG tune. I like the way the stock DGS programming holds gears, upshifts and downshifts. The car just flies up over hills and has tons of power at light to medium throttle. As a benefit, the turbo whine I have been hearing for the last year or so seems to have largely disappeared.
