In that case then correct, because when high boost cannot tune lean. My friend fried his SR20 engine by boosting too high, but fuel feed not enough....what i mean is not that the fuel consumption can be better, its just need to tune to know that with all the fuel pressure and mapping is it ok or not with current boosting.. at least we know are we running too lean or too rich.. then it would be wasted if we're giving too much fuel for nothing. even the engine response would be affected also if were running rich. am i rite bro vr2?
