This is an Audi TT Gen3/MQB 2.0 TFSI DSG6/DQ250 with a CTS Turbo Boss500 kit, which utilises the Garrett GTX2867 turbocharger. A Water-methanol injection kit together with 98RON complete the package for making good power on all 4 wheels. The Boss500 CTS turbo kits have a nasty habit of not boosting and working very well
