Do I Need An Aftermarket ECU To Tune My Commodore?

NO, we recommend staying with the factory-fitted ECU/PCM as these are very tuneable.  In fact, many of the aftermarket ECUs are primarily designed for max power applications and they don't provide any of the cold start, stop/start driving functions that the factory ECUs do.  We have seen the factory ECU used on engines with basic bolt-on mods to high-performance blown engines without problems producing just as much power as aftermarket ECUs can.

Fitting an aftermarket ECU is also a very costly exercise.  Many aren't a simple "plug & play" setup.  First, you need to purchase the ECU, then you need to have it wired in and then it still needs to be tuned.  We believe in using the factory ECU/PCM, then using the extra leftover $$$ on other performance-enhancing parts.
