The DSG remap is a requirement as the torque limiting on ED30's and S3's does prove a problem.
My K03 hit the in-gear torque limit (not a problem in itself), but it was the post shift lag that frustrated. On a stock map, or Revo stage-1 I have not experienced the same post-shift lag annoyance.
As a slight aside, if g/s readings from the MAF are a fair comparison of torque and power, then on the Revo calibration my engine is producing more of both at any given point in the rev range. If anything the Revo cal' should be causing more gearbox woes than the Shark map did, but it is absolutely fine.
I wanted to be impressed with the Shark map, and wanted to try an alternative to the default Revo option - good to help the smaller companies and encourage competition. Sadly it proved a poor investment.
Maybe, just maybe I was sent the wrong map for my engine / gearbox combination, but whatever the situation my concerns weren't ever resolved or dealt with in what I'd consider an appropriate way.
So if you have dsg and want thd shark map you also have to get dsg software! That makes an expensive map
Which can't be applied by the STS as I understand things, so dictates a visit to Shark HQ or one of their agents. Limits the appeal to many I should imagine.
I had the option at the point of experiencing post-shift problems to stick with the Shark engine map and apply the DSG map to "cure" my issue. After the thread on this forum, and sniffing around elsewhere, I concluded that I shouldn't have a problem with just the stg-1 which in my mind threw the competence of Shark into question.
For the benefit of the OP, this is the thread in which the post-shift woes were discussed.
