  • Stage 1 - Shifting optimizations with stock line pressure. If you are already running an EPC fooler valve or built transmission to increase line pressure, this is the option you want.
  • Stage 2 - Line pressure increase with no change to any other parameters. If you like how the stock transmission calibration shifts, but want to increase your transmission's line pressure to hold more power, this is the option you want.
  • Stage 3 - Shifting optimizations + increased line pressure. If you want to get the absolute best performance out of your stock transmission, this is the option to choose.
