My 99 2.8 (M52tu) Z3 Coupe dynoed at 169hp and 171ft lbs at the wheels... stock. Mustang dyno, South Florida heat. That said, from what I understand the vanos unit could be your whole problem. I have a stage II kit from Dr. Vanos waiting to go into my S50ti, it makes minimal power in the low end but comes alive in the high RPM. Do you have any fault codes? __________________ SUPPORT 318ti.org! CLICK THE LINK ABOVE!
