The above listed maximum engine horsepower levels should be reduced by

roughly 10% in order to allow for enough fuel to run the jet pump that

fills the fuel canister. For the jet pump to operate correctly, Lingenfelter

does not recommend lowering the fuel pressure on the GTO with the use of

aftermarket adjustable fuel pressure regulator kits.
