With the ability to choose between a dry nitrous progressive or up to 6 stages of nitrous the options are endless. You can even combine the dry NOS progressive and the staged setups for as much nitrous as your motor can handle.

  6. Nitrous and Fuel Time Delays based on the nitrous being activated
  7. Ability to add a Lambda value offset to the base engine AFR table
  8. Individual cylinder fuel and spark control per nitrous stage
  9. Ability to choose which nitrous stage to start back with in case of going below the TPS% enable setting
