Shouldn't have had a "nasty" lean spot with 2 shims with the setup you have.

Have you adjusted you idle mixture screws? They should be in the 2.5 turns out range, or pretty close.

The plug color would give you a general indication of the overall mixture.

Removing the snorkel isn't always an improvement. If you were looking for better mileage, I'd try with it back in.
