Here at Diehard Diesel tuning, our core business is working
on your car. Whether all you want is a basic tune – such
as taking the 90bhp Peugeot 306 diesel engine, up
to 120bhp with no mechanical changes or a full
race engine building, setting up and installing
– we can tackle it all.

We can also carry out chassis work and upgrades, such as
brake changes,
rear beam suspension adjustment
front Spring / Damper changes



As well as the fantastic services we offer on our premises, we also offer mobile fitting and tuning services. If you can’t get to us, call us out


and we can tackle various mechanical jobs on your turbo diesel – whether it’s a suspension swap, or changing over to the much sought after Bosch fuel system on a Peugeot/Citroen XUD engine – we can do it… mobile!
