Stage 3 Performance Engine Software has been tuned specifically for use with Dinan's High Flow Throttle Body optimizing power output as well as improving drivability. The software safely raises the rev-limiter by 250 RPM and 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 throttle body): Max gains of +14 HP and +12 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
