No, no, no. Set it to like -1000 feet and you will pick up some serious HP from the denser air.

That would be for the heads up guys.

Street guys need to be around 2500ft, also need carb heat on and the mixture set rich so not to freeze up.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.
