We offer the full spectrum of upgrades, from forged engine builds to turbo upgrades, high capacity injectors to front mount intercoolers we're experienced in all areas of tuning and upgrading and have access to upgrade parts from the world’s most respected companies such as HKS, Blitz, Cosworth, Roger Clark and Turbo Dynamics

Alongside engine tuning and performance upgrades we also offer in-house re-mapping of the Subaru ECU to ensure safe running whilst extracting as much power as is safely possible from the engine, using Ecutek software. At Scoobyworks we're authorized Ecutek dealers.

The re-mapping process involves loading a new ‘map’ into your Subaru’s ECU to enable the timing, boost, fuelling and air intake to be correctly setup for safety and increased performance, whilst ironing out any potential flat spots or problem areas.

We also offer several Tuning Packages for both WRX and STI models, at discounted prices, see below for details.

All re-mapping is carried out on our 4wd Dyno Dynamics Rolling road, for safety, consistency and accuracy. When complete the vehicle is then checked on the road and only when we're 100% happy with the setup is the mapping complete.
