Which engine gains most?
The turbocharged T-GDI and 1.6T units, by a clear margin. The naturally aspirated 2.0i gains considerably less.
Is it the same as the Optima?
It is the same car sold under a different name by market. Our experience with one applies directly to the other.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
