Turbo chargers trap exhaust heat and flow to drive the compressor, creating what are termed pumping losses caused by exhaust back pressure working against the piston on the exhaust stroke. The fuel injectors spray fuel directly behind the intake valve into the intake manifold. A forced induction engine also requires more fuel to support HP developed in the cylinder but lost to the work required to drive the compressor helping to make the extra power. This fuel mist is combined with air at a precise ratio, then ignited to create the combustion. While this symptom is commonly associated with fuel pump problems, it can also be a sign of bad gas.
