stupid questions

#2875

built, not bought
i shouldn't have bought an OBD interface and software; now i really don't have a clue.

i never have a value for EGR, is this normal with a stock chip?

what is the difference between MAP and vacuum and how can i have both?

how much should vacuum drop on a non-boost start from stop? does anything hold vacuum after crossing into boost?

a non-boost start in my vocab is when the brake and throttle are never used simultaneously
