How your tune happens

Order and confirm Add the tune to your cart or request a consultation. We confirm your exact year, engine and any hardware already on the car before anything is written.
Flash method Depending on the platform, the tune loads through the OBD port with a handheld flasher we ship to you, or the ECU is unlocked once on the bench at our Sugar Land shop. The brand notes below say which applies to your car.
Calibration Your file is built for your engine, fuel (91 or 93 octane) and hardware. Stage 2 files assume downpipes are installed; if yours are not, the downpipes for your car are listed on this page.
Datalog and revise After the first drive we review logs and adjust. Revisions during the break-in period are included.
Support Return to stock is always available. Questions before or after: email us and we will get back to you.

McLaren 570S, 600LT, 720S, 765LT and GT run Bosch MED17 ECUs that flash through the OBD port with a handheld we ship or at the shop. Stage 1 is software only on stock hardware. Stage 2 is written for high-flow downpipes and needs them installed. Files are built for 93 octane; tell us if you run E85 blends.

Stage 2 is written for downpipes; the ones for your car are listed below
