Product Description

Package includes:

  • MMS Standard PCM
  • Modular pulley system with one pulley of your choice, although we suggest 3.4" be the smallest you choose unless you have more mods including headers, and fuel system upgrades
  • 2.5" T304 stainless downpipe without cat (with cat also available for additional cost)
  • Gatorback supercharger belt matching the pulley size specified and your vehicle
  • 180 degree thermostat
  • AL 104 plugs (recommend gap at .050")
  • Optional billet EGR delete kit
  • Optional additional upgrade package: 1.9 roller rockers (stock is 1.6), 90lb valvesprings (50% stiffer than stock), chromemoly pushrods, 60lb/hr injectors, Walbro 255 fuel pump, and additional tuning to go along with these modifications.


 With the above list of standard mods (not including the optional valvetrain mods) with a 3.4" supercharger pulley, you should see gains of around 40 crank hp, or about 32whp.  With the rockers, valvesprings, and pushrods, you should expect a 80hp gain over stock, and the fuel system modifications included will give you room to breathe to add more mods without fear of running out of fuel or needing a re-tune.

The $100 core charge is on the stock PCM, and is refundable once we receive the stock pcm in good usable condition.
