I'm not surprised to hear about modded 3.4 lean issues at all. You should be completely out of injector given the math.

**edit**

I just found that fuel pressure in a 996 is actually 55psi, so that should give a little more headroom, like 6 more bhp.

I'm surprised Porsche put such a small injector in these cars. I've always been under the impression you really don't want to run an injector more than 80% IDC just so you have some additional margin. That would mean you really want an injector around the 290cc mark. That would run a motor comfortably at 300bhp and give you room to grow up to around 370bhp.

So the real question then is if Woody's boxster is setup up for 55psi or not.
