Stealthwerx Tuning

Pumaspeed Dealer for East Anglia and the South East for all fast Fords in particular Fiesta and Focus ST /RS , based in Norwich , offering bespoke hardware and proven software solutions from MaxD.

Our unique approach is based on years of previous experience - This can be dated back to as far as the mid 90's!

The fundamentals and basis for our company and the techniques we apply to each car came to fruition when Ford released the Fiesta ST hot hatch back in 2013.

Its popularity has spawned a large number of 'DIY' tuners but little technical background when it comes to problem solving and getting the best from every car.

Fortunately, this is one area we excel - Problem solving and diagnosis is our speciality.

When it comes to tuning or modification for your Ford, we have you covered.

We have been fortunate to have tried many products and software options on the market, testing them to the limit on the road, track and dyno, and our recommendations are based on this experience.
