Stage 1 accounts for 3 files. The ECUs are Denso references including 76F00XX. Being naturally aspirated, the gains here are modest by nature.

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.
Does it affect the four-wheel-drive system?
No. The work is done on the engine ECU and does not alter the transfer case or the low-range gearing.
Is the work reversible?
Yes. We always keep the original ECU file, so the vehicle can be returned to its factory configuration.
