Why Choose ECU-SHOP Products

The Best Tunable ECU Solutions

Our piggyback tunable ECU units like the ECU-SHOP Ultraboost enable professional tuners to extract more power, more torque and reduce fuel consumption in turbocharged diesel engines.

Our Piggyback ECUs come with a Plug and Play Loom which means there's no hacking into your precious factory loom, ugly solder joints or tap wires. This also means when it comes time to sell your vehicle, the loom is simply unplugged and the factory loom clipped back in again.

Often it's just a new loom for $395 that is needed to enable you to transfer the Ultraboost to your new Ute or 4x4 vehicle (ask us for clarification if you're selling your Ultraboost-equipped vehicle)
