Product Description

Package includes:

  • MMS Standard PCM
  • 2.5" T304 stainless downpipe without cat (with cat also available for additional cost)
  • 180 degree thermostat
  • AL 605 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, 36lb/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), you should see gains of around 25 crank hp, or about 20 whp.  With the rockers, valvesprings, and pushrods, you should expect a an additional 20-25 crank hp, 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.
