Transmission slipping at 3000 rpm is the only problem to date.
Put a new computer chip in, increases hp to approx 190, 200 lbs torque. WOW, when this turbo kicks in (4500rpm) it really pulls hard!!! Handling is first rate, MXV4's stick well except in snow.
What ECU chip tuning did you use? I'm in the process of purchasing one myself for my 99 Passat 1.8T GLS.
