What Tunit Performance Tuning does

Tunit Performance Tuning (legal entity MDP TECH LIMITED) is a UK-based automotive hardware manufacturer founded in 1998 in Chorley, Lancashire, that designs and sells external engine management tuning systems for diesel, petrol, commercial, and agricultural vehicles. The company's core technology connects to vehicle electronics via original manufacturer plugs without modifying ECU programming or removing manufacturer safety limits, using proprietary "Unique Load Calculation" software to deliver performance and fuel-economy gains simultaneously; the 9-position external dial, smartphone app control (iOS/Android), and dealer-accessible laptop software enable live and bespoke tuning. Key product lines include the Advantage 3 flagship diesel tuner, Optimum/Optimum Plus for petrol, Power Pedal Pro for throttle response, Advantage C-24 for commercial trucks and buses, Advantage A-24 for agricultural tractors and telehandlers, and the Tunit Emu emissions-emulator and Error Delete diagnostic lines, plus a refurbished secondary channel.

Pricing is one-time hardware license per module, ranging from £99 ex VAT for refurbished units to £900 ex VAT for premium emulators, with consumer payment plans (18/36 months) and a Try Before You Buy dealer scheme; revenue streams include diesel tuning, petrol tuning, throttle tuning, commercial vehicle tuning, agricultural tuning, emulator products, refurbished units, branded merchandise, and dealer installation services. The company has remained entirely self-funded since founding, has never taken external investment, employs approximately twenty staff across Sales, After Sales, Service, R&D, and Marketing, and is led by Managing Director Michael Bromley. Customer outcomes are documented via an independent survey of 9,000+ users reporting 12% average diesel fuel savings (5% for petrol), verified by a university study, with payback periods of 3-14 months across vehicle categories and zero warranty claims in company history.
