I swapped mine this past weekend, but haven't had a chance to see how she runs. I was working on the exhaust and the pipes were so rusted I couldn't get them off, and of course I had already grinded the exhaust pipe in half so it was just a header and no down pipe. Needless to say I had to get it towed and don't have it back yet.
Getting shop to do the headers while they're at it.
Also when I did it I figured out why my engine was whistling, the original gasket on the TB was completely gone so air was getting in the space b/e that and the intake manifold.
