Yep, Mikie you're right on. Although both my tuner and Blouch believe that the 18G in my car is capable of approx. 330-340whp (it flows 39 lbs/min as opposed to the TD06 18G that flows 40 lbs/min). In fact, the PO of the turbo was making 320 whp on the very same turbo. I just need to track down my problem.
After I fix the car, my next performance upgrade will likely be this:
