Step-by-step instructions for installing the best in supercharger systems.
1. First off, refer to the included Flashpak manual and flash the Hummer’s computer with the updated calibration for the supercharged system. Should you receive an error code, contact us before proceeding.
2. With a 10mm wrench disconnect the negative (-) battery cable and wrap the terminal end with electrical tape. Ensure that the cable is far enough away from the battery, that it does not accidentally touch the battery and make contact during the installation.
3. Relieve the pressure in the fuel tank by re- moving the fuel filler cap.
4. On the right (passenger) side of the intake manifold, locate the fuel pressure test port. CAUTION! The fuel in the system is under pressure! Relieve the pressure in the fuel system by depressing the check valve with a screwdriver and collecting the fuel with a shop towel. Magnuson Products recom- mends that you wear eye protection to avoid injury.
5. When the engine is cool, slowly remove the radiator reservoir cap. Do not remove the cap if the engine is still hot or serious injury may result.
6. Remove the engine oil cap. This cap needs to be removed before removing the engine cover. Put aside, this cap will be reused.
7. Remove the engine cover completely, as it will not be reused. After removing the engine cover, replace the Oil Cap to ensure no debris gets dropped into the engine.
8. Loosen the air tube clamp with a 8mm nut driver.
9. Loosen the Mass Air Flow meter (MAF) clamp with a 8mm nut driver.
10. Remove the PCV vent pipe from the front, top barb of the passenger (right) side valve cover.
