Focus Mk3 ST Diesel

PUMASPEED - The Home of Focus ST Diesel Tuning

The Focus ST Diesel has always been a firm favourite in the Pumaspeed office, with the cost of buying becoming ever more affordable, it's a car that with a simple remap has proper hot hatch performance, whilst maintaining fantastic fuel economy, what's not to love? Since the Focus ST Diesel release in 2015 we have owned 2 development cars over the years, our original white development car which was taken all the way to stage 3 with 280bhp and 600nm! and our current stage 2R tangerine scream car running a petrol ST bashing 250bhp and 520nm.

Due to being in the fortunate position of owning these two development cars, we have been able to test every product on the market, and design plenty of our own, meaning we really are at the top of the tree when it comes to the Focus ST Diesel tuning world.

Pumaspeed truly is the home of Ford tuning, starting with the Pumas in 1999 and now this year buying a Mk4 Focus ST, the new Puma ST, Mk8 Fiesta ST and branching out into the BMW, Toyota and Hybrid markets, our MAXD Out remapping software is unrivalled and the R-Sport hardware we stock is second to none. So whether you have just picked up your ST Diesel and you're looking to pack a little more punch from your turbo with our stage 1R remap, or you're looking for a fully fitted stage 3 X37 hybrid turbo kit, you know you're in the right place! 

See below the Performance Tuning Packages suitable for your Focus ST Diesel
