Mark Oldfield brought his Sierra Cosworth in to us after a rebuild. Some dyno time was required to solve an idle issue and also to bring the boost up to a more powerful but safe level. As long as its safe for the engine we generally start off on a lower pressure and work our way up in increments until the customer is happy with the power the car is producing. The car finished at 425BHP which is more than enough to push this RWD Cossie along nicely.
