Question Question about boost controllers

If you increase a car's boost (if it makes any difference let's suppose it's a BF turbo legacy 2.0 1994/1993, the ones with intercooler) with a boost controller, I suppose more air enters the cylinders right? So does the car (or the boost controller or whatever, I don't know) adjust the fuel injection to keep the mixture from getting lean? Do you need to install anything extra if you get a boost controller?

thanks,
Kotaro

When you increase the boost, the engine, via the O2 sensor, sees that there is a different air-fuel mixture, and increases the amount of fuel going in.

There's no need to get an air-fuel computer if you're just increasing boost slightly, but it could be used to lean out the mixture and make more power.
