Hi all ZF 6HP26 Gearbox owners, I'm pretty proud to be one of the first in Australia to have my ZF professionally tuned with the latest software from Herrod. It was done last Tuesday at BluePower and I've gotta say, I'm never going back to STD. Gear changes are sharper and shorter, no thump what so ever going down from 2nd to 1st. My brother and I took it for a road test today to play around with it and we were both immediately responsive and ecstatic to the differences in all styles of this tu
