More Power

Plug-in the diesel tuning box and feel the extra power - instantly. Up to 40% more power means a sharper throttle response. Say goodbye to flat spots and turbo lag. Enjoy a livelier feel, as if you'd chosen the bigger engine option.

Stephen from Essex proved it for himself on his Audi 2.0 TDi and emailed to tell us: Throttle is crisp and responsive, gear changes seem smoother. Absolutely no engine lag... mid range it pulls like a steam train... with no engine labour in the higher gears, so less changing down... I made the decision to go with a diesel based on economy... but now also have the performance of the petrol version. Fantastic!

More Torque

Fit the CHIP Express™ digital diesel tuning system for more torque too. You'll immediately notice better acceleration in the middle gears, from low down in the rev range. And that means more pulling power - precisely what you need if you tow a caravan, a horse box or a boat. Or if you drive a heavily laden vehicle like a van or pickup.

Don't take our word alone - listen to Robert from London who told us: After fitting the tuning box my van gained a lot of extra low-end grunt... carrying heavy loads is now effortless and I get much better economy.

Better Economy

With ever-rising fuel costs nowadays, you'll appreciate up to 20% better economy. Greater power and torque means you'll change up through the gears much sooner and change down less often. Auto boxes will respond in the same way too. This keeps your RPMs lower and saves you fuel.

Nick from Tamworth noticed exactly this and wrote to tell us about his impressive 21% fuel economy improvement: We towed the caravan earlier today and noticed it was much easier to pull and the fuel economy was much better - when we picked it up we got 33mpg but now we're getting 40mpg.

And best of all, if you wish you can remove it just as easily, leaving no trace it was ever installed - so no worries about your manufacturer's warranty.

The CHIP Express™ digital diesel tuning system is not a "replacement chip" where your ECU is physically opened and its original chip replaced (thus immediately invalidating your vehicle warranty). Nor is it a "remap" whose settings can be detected and even deleted during routine servicing. The CHIP Express™ plug-in digital tuning system is a sophisticated microprocessor controlled tuning system which will give you substantial, immediate performance and fuel consumption gains.

Whether you drive a manual or an automatic, a car, van, motorhome, tractor or even a boat, we have a diesel tuning chip for you - just check out our vehicle finder now to see if yours is listed!

There are no wires to cut, no special tools needed: you simply plug it in, following the detailed, vehicle-specific photographic instructions provided. The system is designed to give optimum results right out of the box without needing additional complicated setting and tweaking.

Timothy from Stoke On Trent puts it better than we can: I fitted it that evening in less than 5 minutes thanks to the easy and accurate instructions and photos. The difference is staggering; the torque is huge giving blistering performance...

Play

Chris from Essex with a 2.0 TDI emailed to let us know how happy he was with our plug-in tuning system: The change from standard is amazing, loads more torque, better throttle response, increased MPG and a joy to drive. Once again many thanks!
