TUNING THE MITSUBISHI 4G63 (EVO 9)
A nice, straightforward tune session on this Mitsubishi 4G63 EVO 9 GT. The modifications were clean and well chosen: a new exhaust from the turbine back, a panel air filter, and an independent electronic boost controller.
With the hardware in place, we reprogrammed the factory ECU to suit the new modifications and revised boost level. The custom factory ECU remap was carried out on the dyno to ensure everything was dialled in precisely for this combination.
The result is a nippy, responsive EVO 9 GT that is perfect for daily driving. It has more power and sharper response, but remains smooth and easy to live with every day. A great example of a well-executed fast road tune on an EVO 9.
