The present invention is directed to a system and method for controlling an engine braking system having an engine with at least one intake and exhaust valve, intake and exhaust manifolds, a turbocharger connected to the intake and exhaust manifolds, and at least one pressure regulation valve. The method may comprise the steps of measuring a value of an engine parameter; adjusting the pressure of the exhaust manifold responsive to the measured engine parameter value; actuating the at least one exhaust valve; and adjusting a pressure gradient across the turbocharger.

A spacer according to claim 10, wherein said corrugated openwork mat is elastically compressible and compresses up to no more than about 30% of its original thickness when subjected to about 100 to about 200 pounds per square foot (psf) of pressure. 12. A spacer according to claim 11, wherein said corrugated openwork mat has about 4.0 to about 8.0 ounces of polymeric filaments per square yard of said openwork mat. 13. A spacer according to claim 12, wherein, when said mat is unrolled into a substantially planar condition, each of said ridges on said front face has an apex which extends to a common front imaginary plane, wherein each of said ridges on said rear face has an apex which extends to a common rear imaginary plane, and wherein said front and rear imaginary planes are substantially parallel and are spaced-apart a distance of about 1/8 to about 3/4 inch. 14. A spacer according to claim 13, wherein each adjacent pair of said apexes on said upper face and each adjacent pair of said apexes on said rear face is spaced-apart a distance of about 1/8 to about 3/4 inch. 15. A building structure having drainage passageways and air spaces therein to prevent moisture from being trapped within the building structure and to retard deterioration of the building structure, comprising: an inner sheathing member; an outer building material; and an elongate corrugated web of openwork material located between said inner sheathing member and said outer building material for providing drainage passageways and air spaces therein to prevent moisture from being trapped between said inner sheathing member and said outer building material; said corrugated web having an undulating front face, a corresponding undulating rear face, and a pair of longitudinally-extending side edges each having a serpentine configuration, said pair of side edges being substantially parallel and being installed in the building structure such that said side edges extend substantially parallel with the horizontal, and said openwork material having a plurality of openings permitting free passage of air and liquids in both transverse directions therethrough between said front and rear faces; and each of said undulating front and rear faces having an alternating array of ridges and grooves which extend continuously from one of said side edges to the other of said side edges such that said grooves on said front and rear faces provide substantially vertically-disposed, continuous, unobstructed drainage paths within the building structure. 16. A building structure according to claim 15, wherein the building structure forms a wall of a building. 17. A building structure according to claim 15, wherein the building structure forms a roof of a building. 18. A building structure accord
