Mercedes Benz new 3.0L V6 Biturbo has proven to be a great platform for performance tuning. The GL450 comes standard with 362 Horsepower and 369 Torque. After tuning we saw huge gains of +124wTq @3600rpm and +106wHp @4600rpm to all 4 wheels on a 4×4 Mainline Dyno. An unmodified GL450 running CA91 premium pump fuel was dyno tested.  Gains can be seen on the pictured graph below, the unmodified Baseline (Blue) vs OE Tuning ECU Tune (Red).
