How much does a naturally aspirated V6 gain?
Considerably less than a turbocharged engine — there is no boost to adjust. We are honest about this: expect refinement in delivery, not a large power figure.
How does it differ from the IS 220d entry?
The 220d is the diesel version of the same car, with a very different service profile. Each has its own entry.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
