We work on a few of our dealership cars that are for sale. First we needed to get the ECUs back in the F430 Turderia, and swap the pedal potentiometer back out of the 575M. Then we get the Turderia out on the road to verify that the new tune works properly. After that, we swap out the original air filters on the McLaren 650S for some K&N air filters. While doing that, the convertible top on the Turderia breaks again leaking hydraulic fluid all over. Finally we try to attach a new spoiler on the Porsche Boxster S, but it turns out that we ordered the wrong one.
