I guess my point is, what is the affect on the gas tank pressures/vacuum if removed? Along with a stock ECUs predetermined calculations for lean/rich when it commands a purge, much like EGR...

With all of the threads concerning charcoal canisters on this site, you pick a thread NOT concerning them to ask a question that's been asked (and answered) 2 dozen times here to make your first post....?

I recommend making a proper intro thread and using the search function afterwards.

No. Removing the charcoal canister will allow hydrocarbon vapors to escape from the fuel system and contaminate the earth's atmosphere, contributing to smog formation, acid rain, and ozone depletion. All of these things are unsafe.
