The badge says 720.The dyno says 920.
One twin-turbo architecture, enormous headroom. From the MP4-12C to the 765LT, we unlock what Woking left on the table — up to +232 hp on completely stock hardware.
Select Your McLaren
Fourteen McLaren platforms, MP4-12C to 750S. Pick yours and see the numbers.
Pick your model and the real dyno figures appear here — 14 McLaren platforms, gains up to +232 hp.
The files we're known for.
765LT
The Longtail with the leash off. 955 hp at Stage 2 — the M840T doesn't flinch.
720S
The most underrated engine in production. The badge says 720 — our dyno says 920.
600LT
The M838T's final form. 765 hp at Stage 2 turns the junior Longtail into something senior.
One architecture, fully unlocked.
3.8L Twin-Turbo V8
MP4-12C through 675LT and 600LT. Every variant runs the same conservative factory logic — our files take all of them past 730 hp on stock turbos.
4.0L Twin-Turbo V8
720S, 765LT, 750S, Senna, Elva. Enormous factory headroom: +130 hp from software alone, +200 and beyond with bolt-ons.
7-Speed Seamless-Shift Gearbox
TCU calibration for the Graziano SSG — clutch clamp, shift aggression, and launch strategy that keep pace with the new power.
Bench-Flashed, Done Right
Most McLaren ECUs are read and written on the bench — precise, verified, and your factory file is archived before anything changes.
Every tune, every detail.
ECU Calibration
Ignition timing, fuel delivery, boost, throttle mapping, torque limiters, rev limiter — written from scratch for your exact platform, never pulled from a database.
TCU Calibration
Shift maps, clutch pressure, torque passthrough, launch control, and gear-hold logic — matched to the engine file so the gains reach the wheels.
On-the-Fly Map Switching
Four map slots toggled from your factory cruise control stalk. Valet, street, race, and custom — no laptop, no aftermarket hardware.
Engineering Support
Direct access to the calibration engineer who wrote your file. Not a call center. Not a ticket queue. The engineer.
Answers, straight from the engineers.
How much power can my McLaren gain?
+
More than almost anything else we tune. Stage 1 software takes a 720S to 850 hp; Stage 2 with exhaust work reaches 920. The M838T cars (12C through 675LT, 600LT) all clear 730 hp. Select your exact model above to see real figures.
Can the stock turbos and internals handle it?
+
Yes — that's the point of the McLaren platform. Woking engineered the M838T and M840T with margin the factory calibration never uses. Our files raise boost and torque inside verified mechanical limits, validated on the dyno before delivery.
Do you tune the gearbox too?
+
Yes. The Graziano SSG's factory calibration enforces stock torque limits and soft street shifts. Our TCU file raises passthrough limits and sharpens shift and launch behavior to match the engine calibration — on a 900 hp car, it's not optional.
How is the tune installed on a McLaren?
+
Most McLaren ECUs are bench-flashed — read and written directly with your factory file archived first. We handle it at our Conroe, TX headquarters or through an authorized Stage 4 dealer.
Which McLarens do you support?
+
Fourteen platforms: MP4-12C, 540C, 570S/GT, 600LT, 620R, 625C, 650S, 675LT, MSO HS, 720S, 750S, 765LT, Elva, and Senna. If yours isn't in the selector, contact us.
