Everything you just said is completely wrong. The mass air sensor will probably need to be recalibrated or replaced to match the injectors, but the mass air sensor just tells the computer how much air is flowing into the engine so the computer knows how long to keep the fuel injectors open. Without a good tune the computer won't know what to make of the extra (pressurized) air and will run extremely lean and blow s**t up. more air does not equal less gas, its actually the opposite. If you cram more air into the combustion chamber the more fuel you need. This is why when you increase horsepower you also need to step up to larger injectors. Your fuel economy would not change if you kept the car out of boost, but who is going to do that?Originally posted by "BioHazard"
well if you look at your explanation of "turbo threshold" and turbo lag, they sound pretty much the same to me, i dont know about you people...and as far as the A/F ratio, your mass air sensor should accomadate for that...just call a performance shop that sells them and tell them your boost(psi) and the psi of your injectors, and they can match ya up with one that will work just fine. Also by installing a turbo you overall use less gas...More air in the combustion chamber = less gas, and since the air makes the compression greater you still get more power...just a few things i noticed that were explained incorrectly.
