todays VAG 1.8T's are DI but older ones like i have + had were not. my 2001 TT 225hp stock is said to be able to handle 400 hp + good torque with stock internals, its the big torque down low thats hard on engines, drivetrains + clutches. there was a special slightly weaker tune for newer DSG cars. Vag advertised power outputs were conservative as APR dyno's show stock wheel power output matching advertised power outputs! turbocharged subarus in the past were very weak until higher rpm to protect their somewhat fragile awd drivetrain. i tested a 2001 WRX in 2001 + it felt doggy compared to the 2001 1,8T jetta i bought with only 150 hp + 162 TQ advertised, subaru also felt like a tin can compared to the VW IMO!!!
