M838T ProTune

We are now offering remote Pro-Tuning for all of our customers who have purchased the M-Tuner Calibration Suite for M838T. 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 M838T Motorsport Features Package at no additional charge.

For this purchase, a liability waiver will need to be signed and e-mailed to us. Here is a link to the waiver:
