Custom Tuning Surrey

Custom Tuning Sessions

If you’ve a heavily modified vehicle, for example, upgraded turbocharger, injectors, supercharger etc. (or for anything custom built), it’s safe to say you’ll need the car remapping on the dyno. The reason for this is that your modifications will likely be unique and require tweaking more than a stage 1 or stage 2 tune.

Who Needs A Custom Tuning Session?

A dyno or rolling road is an effective and safe way to determine vehicle behaviour as if it was being driven on the road.

Our 2wd Dyno Developments rolling road is also capable of steady-state tuning, meaning we can hold the engine at a particular RPM to see how it behaves in the event that the car is experiencing flat spots or issues at a particular rev range.

We provide custom tuning sessions for heavily modified vehicles. This is an all-day session on the dyno where we provide multiple file revisions until we’re happy with engine power, safety and vehicle behaviour.

Please note, despite our system being 2wd and not 4wd, we are still able to run most modern 4wd systems as one of the axels can be disengaged and have all of the power sent to 1 axel.
