M840T PROTUNE

We are now offering remote Pro-Tuning for all of our customers who have purchased the M-Tuner Calibration Suite for M840T. For those of you who are looking for every ounce of safe power out of your McLaren, or have parts configurations not specified in our map notes, we can now customize your calibration remotely or at our South Florida Dyno Facility.  Due to the complexity of adding injectors or upgraded turbos we charge an additional $250 for McLarens with upgraded fuel or turbo systems.ProTuning will also include the enabling of our M840T Motorsport Features Package at no additional charge. *M-Tuner is required for ProTuning Services. *Using a dyno is highly recommended and in most cases required for ProTuning. Dyno rental costs are NOT included with the purchase of a ProTune. Please refer to your local dyno facility for rental costs. M-Engineering is not responsible for any costs associated with renting and scheduling a dyno. Please reach out to us if you'd like to schedule a dyno
