TUNING: See specifications below. Click here for tuning procedure.

Tuning Specifications below are a guide only. Local conditions and vehicle specifications may demand alteration of the values below.

Boost Level: 10-12psi @ 3000RPM full load/full throttle measured at intake manifold or crossover duct.

  • More Wastegate Actuator Pre-Load (Shorten Rod) = Higher Boost
  • Less Wastegate Actuator Pre-Load (Lengthen Rod) = Lower Boost

Max Exhaust Gas Temperature:

Full load/full throttle at 3500RPM - 4000RPM after 1min at full load/full throttle

  • Measured in the EGT Port (in the turbocharger inlet - Preferred position) = 650 deg C
  • Measured in the engine pipe (after turbocharger - Not Preferred position) = 500 deg C

Air Fuel Ratio (AFR)

  • 1000RPM = 15.5:1 - 16.0:1 at full load/full throttle
  • 3000RPM = 20.0:1 - 20.5:1 at full load/full throttle

NOTE: Higher AFR ratio numbers result in cooler and more reliable engine operation.

  • To lower AFR number (increase fuel delivery rate) turn main fuel screw clockwise.
  • To increase AFR number (decrease fuel delivery rate) turn main fuel screw anti-clockwise

Maximum Speed Governor

  • 4200RPM - 4300RPM at full load/full throttle in 2nd gear
