I bought Stefan Schmidt's 2161 last fall and my Ghia's due for AirCare next month. I'm debating whether to get the car through with the stock 1500 or put the big 'un in and try my luck. It's a fresh, really well-built motor with Spanish 48 IDFs and a TechEdge wideband, so tuning it shouldn't be that hard.
I just have zero experience with webers, and frankly I have more money than time to screw around with it.
Can you give some more info on the Bug Shop? Address? Owner name?
