QST Stage 2 ECU Tuning Software Mclaren 540C 570S 570GT

We are thrilled to extend our 30+ years of tuning excellence in to the Mclaren market. The Mclaren's are absolutely phenomenal cars right out of the box and with a few upgrades we can turn them up a notch, adding effortless HP and TQ across the powerband with improved drivability.

Our Stage 2 ECU software upgrade after countless hours of development both on the dyno and the street gives gains of up to +140HP +140NM on the 570S/GT models. Taking the cars up to 708-720HP and 720-740NM of torque with no additional upgrades required.

Stage 2 required a minimum of a downpipe upgrade, we recommend our Race downpipes.

Power figures advertised are using our Full race exhaust system, ITG air filters and 99ron pump fuel. Tested on a Dyno Jet dyno.

For Stage 2 power levels we advise replacing your spark plugs and coil-packs depending on the model year/mileage of your Mclaren.

We require your car on-site at our HQ for a day, tuning is developed for 99ron fuel.

We can also tune your car if you remove your ECU and send this in to us, our tuning is all developed and tested, please contact a member of staff to discuss.
