Well done Percy.

True.  The GReddy is not a real 0-60 setup.  I love steep uphill grades on
the interstate.  You can pull to redline in fifth going up a steep hill
with no problem.

I'm watching the Link A/F meter and running 6psi.  Need to order adjustable
FPR & gauge with isolator before thinking about messing with boost.  
The FM ECU is a distant vision ATT.

Try replacing the casting on the turbo outlet.  Use a 2 inch steel pipe
bent in an "S" shape.  It increased boost significantly and helped flow
noticably with mine.

Probably next year...
