The accelerator will open the butterfly in the throttle body to allow more air, the computer will measure how much air is being forced into the engine per stroke and inject the required amount of fuel to achieve a clean burn as predetermined by the ECUs' fuel-air mixture mapping. This results in increased engine speed which correlates to increased exhaust gas flow which in turn increases the rpm of the turbo which THEN increases the boost pressure incrementally as the engine gains speed until peak boost is reached and the wastegate is actuated. What you're referring to is called laboring the engine, which is only 'undesirable' as it won't actually damage anything other than the drivers' pride if they don't compensate for the lack of power at low RPM in a high load scenario and actually stall the vehicle. The most common high load scenarios encountered would be driving on an incline, or attempting to overtake without downshifting. The same applies to N/A vehicles as well. This would be better classified as one of your pet hates, not an actual 'do not do'. (you may be referring to the thermodynamic efficiency of a gasoline engine and its relativity to combustion efficiency in a high load scenario, which is something completely different and has more to do with fuel efficiency than any damage that might occur)

What do you guys think? Is lugging the engine possibly damaging or is it just a dumb thing to do?
