Pre installation inspection with Scan Tool (Verify Condition of Vehicle) 1. It is advised to inspect the vehicle before install the supercharger kit as any potential problems can be found easier before the SC installation. 2. Carefully remove the supercharger system from its packaging and locate the SCT downloader. 3. Connect the flash tool to the factory OBDII port, turn the ignition to “ON”. Read the DTCs and data from the ADVANCED FEATURES prompt. 4. The car that you are installing the supercharger on should not have stored trouble codes. IF VEHICLE HAS A STORED TROUBLE CODE OR HAS A DRIVEABILITY PROBLEM THIS SHOULD BE ADDRESSED BEFORE PROCEEDING. 5. The first data to be inspected is the LONG FUEL TRIMS. This data is a direct correlation of the air/fuel mixture. PERFECT long fuel trims are 0 (this means the ECM is adding no fuel OR not subtracting fuel. In the REAL world the fuel trims -4 to +8 are considered to be correct). 6. With the engine warmed up at idle Inspect long fuel trim Bank 1 (1,3,5,7) and long fuel trim Bank 2 (2,4,6,8), if the data is within -4 to +8 this is normal. 7. (Complete kits only) Make sure your battery is fully charged before installing, if not, install a battery charger to maintain 14volts. Kits not using the Whipple supplied tune are not 50-state legal and are for off-road use only.
NOTE: To insure compatibility It may be necessary to have the ECM/TCM updated by a GM Dealer to the most current stock calibration before the SCT programmer can be installed. It is recommended to do this before installing the supercharger kit.

110. Attach the negative cable to the battery and tighten. 111. Turn the Ignition key on DO NOT START THE ENGINE. Inspect for ANY leaks such as fuel, coolant, and intercooler coolant, correct as required. 112. Start the engine and let it idle for 30 seconds and then shut the engine off. Check the SC oil and correct if needed. 113. Start the engine and let it idle. The engine should idle normally between 600-700 rpm. Inspect for leaks. After running for 2 minutes turn off engine and inspect the level in the ENGINE radiator and the Intercooler tank. With the key in the ON position engine off, inspect the coolant in the intercooler tank, the coolant should flow in the tank. Top off as necessary. 114. Before driving make sure that you have 91 or higher octane fuel in the system. NOT ½ tank of 87 and ½ tank of 91, ALL 91 or better fuel in the system. DO NOT USE ANY OCTANE BOOSTER IN THE FUEL. 115. DO NOT use ANY aftermarket air filter box or duct with the supplied Whipple calibration. The Whipple calibration is designed to work with the factory air box, factory MAF and Whipple air inlet duct and nothing else. Changes to the air inlet system will require a custom tune which Whipple does not provide and is not 50-state emissions legal. 116. (Complete kits only) Install the supplied 50-state legal sticker to factory radiator shroud or on hood near factory emissions sticker. Clean area with acetone or cleaning agent before installing. 117. Note that the ambient air temp shown on the digital display in the dash takes 24 hours to read correctly after the PCM has been flashed. It will read 32deg until that time. 118. Test drive vehicle for the first few miles under normal driving conditions. Listen for any noises, vibrations, engine misfire or anything that does not seem normal. The supercharger does have a slight whining noise under boost conditions, which is normal. 119. Re-check the radiator and intercooler reservoir coolant level regularly over the first 1,000 miles, top off level as needed. 120. After the initial test drive, go through the belt tensioner process again. When next you start driving, gradually work the vehicle to wide open throttle runs. Listen for any engine detonation (pinging). If engine detonation is present, let up on the throttle immediately. Most detonation causes are low octane gasoline still in the tank. Continued detonation can cause engine damage, contact Whipple if you are having this issue.

CONGRATULATIONS Your new Whipple Supercharger is engineered to significantly increase your engines power across a broad range of RPM’s. It is Whipple’s goal to improve your driving experience for many miles and years to come. Whipple Superchargers operate as an air pump and contain internal rotors that are driven by the engine’s crankshaft and serpentine belts. The supercharger compresses outside air and channels it into the engine’s intake ports. Because of their design, superchargers may generate some additional noise over the standard, normally aspirated induction system. At idle, you may hear a medium-pitch rattle from the supercharger main housing. This will diminish at about 400-500 rpm above idle. You may also experience a muffled high-pitched whine during acceleration. This is caused by the pumping action of the supercharger compressing air and only occurs during boost conditions. It is inaudible during part-throttle acceleration. These are normal noises associated with any supercharger and have no effect on supercharger performance or engine durability. Your supercharger is warranted by Whipple Superchargers, please see your terms and conditions on the back of your invoice for more information in regards to the limited warranty. NOTE: Whipple Superchargers will not authorize any warranty repair work or supercharger replacement for normal noise
