Hi there looking for advice on tuning tips for TTRS 8j, DSG, car is only used for competition use,
car currently running stage 2 420 bhp but lacking a bit, I don’t want to go mad I’m looking for around 550 bhp, so looking to find out what’s involved and best people to talk to in the uk
Thanks in advance

Go for a hybrid turbo, like the TTE
