I may be biased because we are Shark Performance dealers as well (Well, will be as of tomorrow) but I spend loads of time on all sorts of forums and a bad review about their software is very rare. I can't say the same for REVO. A lot of people on Audi Sport have switched to Shark, some have DSG as well and don't seem to have any problems.
I'm not saying REVO are no good, they haven't got were they are by making rubbish maps but my S3 has a stage 2 REVO map on and it isn't the best to be fair. I have been saying that since well before I even spoke to Ben@Shark by the way
I've driven a lot of remapped cars and mine has had loads of hesitation problems. Now that could be down to a deeper lying problem with the car being highlighted. We will find out tomorrow when I get the stage 3 Shark map put on
As for the DSG problems, it seems that some cars take to the Shark maps and have no problems but not the REVO & vice versa. Just goes to show that every car is different.
