This question is best answered by a search. We have been turbocharging these cars since they were new.

There's not much to trick on the ECU. 96+ cars will fuel cut when they see boost, so most people add a voltage clamp on the MAP sensor to prevent the ECU from seeing any value above 0psia.

Fuel is usually added in a manner the ECU has no control over, e.g. increasing fuel pressure via a variable rate-of-gain regulator.
