GM L87 6.2L

ECUWEST’s Chevrolet Silverado LTZ 1500 6.2L L87 ECU Remapping for 2019+ models is now available. 288 – 310 Rear Wheel Hp and 50Nm extra torque. Sounds like a real V8 should without droning when cruising.
We will need your vehicle while HPTuners modify and unlock your ECU to enable us to tune it.

We use AFE Headers, Hiflo Cats, 3″ Exhaust and Cold Air Intake. We also use MBRP exhausts, depending on availability.

Procharger supercharger options will also become available as we develop it.

Our specialist tuners set the vehicle up on our All Wheel Dyno for a baseline dyno run. We then through our iterative tuning process, tune and revise the tune until it perfectly suits your car and its modifications. All this is done to a safe industry standard ensuring maximum reliability and longevity.
