Stage 3 Performance Engine Software has been tuned specifically for use with Dinan's High Flow Intake and Throttle Body optimizing power output as well as improving drivability. The software safely raises the rev-limiter by 250 RPM enabling you to carry more road speed in each gear as well as optimize shift points. The top speed governor has been removed enabling the cars to reach their "natural" top speed. Revised EML tuning provides improved drivability by speeding up throttle response.

Features:

  • More Power (with intake and throttle body): Max gains of +23 HP and +17 lb-ft TRQ
  • 50 State Emissions legal; CARB EO # D-176-35
  • 250 RPM rev-limit increase
  • Improved throttle response
  • Top speed governor removed
  • Smooth and predictable power delivery
