The calculator determines the 60' based on the ET, so altitude wouldn't be part of that equation. It already affected the ET, so the slower 60' would follow.

This means the converter is a little tight for the cam and where it is degreed and the car goes aways before it hits it's power band will act like a sudden increase in power like you just gave it more throttle. And add that some vacuum actuated 4 barrels come on what to late with improper spring tuning and sometimes diaphram leaks and other problems. In other words your leaving before the converter flashes?
