More Info

This is a preprepared mod package specific to your car that will give you about 25 horsepower. All of the basic bolt on mods to run a smaller supercharger pulley for more boost. The PCM that is included is our standard ZZP 1.0 pcm with all of the mods listed on its product page. Then a K&N high flow air filter for your stock airbox, works great with the airbox mod for every year and model car except the 97/98 engines, we highly recommend the Stage 2 performance package for those years because it comes with an aftermarket cold air intake because the stock airbox does not flow very well. Then the cooler spark plugs and thermostat will help reduce potential Spark Knock or “KR” that you may get from the increased boost of the Modular pulley system that is included. The modular pulley system will only take a couple minutes to swap pulley when you have the proper mods to run smaller pulleys. 

All packages require 92+ octane gasoline. If not available, please contact us so we can adjust the pulley size specifically for your car.

'04+ Grand Prixs' come with the larger Gen5 supercharger and are more prone to "Knock Retard", so they do not come with a smaller supercharger pulley, and they do not have a ubend so a ubend delete is not needed.

04 Monte Carlo stage 1 kit

Just finished installing a stage 1 kit on my 2004 Monte Carlo Intimidator. While I had it apart I replaced the bearings and coupler in the supercharger and new fuel injectors. I am really happy with the kit. Big improvement from stock.

Great Value for Noticeable Difference

I think the stage 1 package is a good buy. It doesn’t break the bank, easy to install, and there’s a noticeable increase of power. I installed it on my commuter car (03 Park Avenue Ultra), it’s not a performance car by any means but it’ll scoot along pretty well now and still averages around 22 mpg. I would recommend clearing out the better part of your day for the PCM install part of it. For my car it took about 5 tries before the car and the PCM would communicate. Another tip would be to do the air box mod so you can hear some fun supercharger noises. Definitely a fun and easy install overall.
