Those of you who have not been following our thread on the Mercedes forums, We are happy to say that we have finished with our list of planned development works on the E63S W213.

The list of planned work is as follows:

Race Chip Tuning Box GTS


 Air Filters

 Down Pipes


 Wheels Magnesium Light Weight

We bought a Race Chip GTS Black tuning box for our E63S W213 to see how it would match up against the stock figures and also to see how it compares with our planned development works once ECU tuning has commenced, so check the results out below.
