TUNING THE MITSUBISHI 4G63
Tuning two of the same car model on the same day is always a great opportunity for baseline research. We checked engine compression, actuator strength, and boost control status. We also compared exhaust systems, intake setups, temperatures, and even asked the drivers which oil they use.
The EVO 7 got the better of the younger EVO 8 on this first outing. We expect to see both cars back at the workshop for uprated cams and pulleys, then back on the dyno for breathing optimisation.
Great power from an old EVO 7. The Mitsubishi 4G63 is a fantastic engine in stock form. With boost and basic bolt-on modifications, it responds very well to a custom tune. We use Apexi Power FC and other ECU solutions to get the best from each build.
Another happy EVO owner.
