Locked out at 11pm near Heathrow. They were with me in 25 minutes, no damage, cheaper than the dealer quoted. Genuine lifesavers.

Professional. Mobile. Trusted.
Pairing a Stage 1 or Stage 2 engine map with a stock gearbox file is the single biggest cause of clutch-pack failure on DSG DQ250, S-tronic DL501 and ZF8HP boxes. A proper gearbox tune raises the torque-limit ceiling to match the new engine output, sharpens shift speed, removes lazy comfort upshifts, and on dual-clutch boxes can enable launch control and full-throttle shifts. Every tune is custom-written for your specific TCU revision and pressure-tested before sign-off, with the original file archived for free revert.

Frequently Asked Questions
What is gearbox tuning?+
Gearbox tuning is a software re-flash of the transmission control unit (TCU) that increases the safe torque limit, sharpens shift speed, removes 'nanny' upshifts, and on dual-clutch boxes can enable launch control. It's the safe way to pair a Stage 1 or Stage 2 engine map with a stock gearbox.
Which gearboxes do you tune?+
DSG DQ250 / DQ381 / DQ500, S-tronic DL501 / DL382, ZF8HP (BMW / Range Rover / Jaguar), Mercedes 7G-Tronic / 9G-Tronic. Other platforms by request.
How much does it cost?+
Gearbox-only tuning from £249. Paired with a Stage 1 engine map: £180 discount. Custom DSG / ZF8 packages from £349.
Will it damage the clutch pack?+
Not when written correctly. We hold torque within the documented safe envelope for each clutch pack and pressure-test the file before sign-off.
Is the gearbox tune reversible?+
Yes — original file archived, free revert before any dealer visit.
Warranty?+
12-month software warranty on the gearbox file.
