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 ECU's are primarily designed for max power applications and they don't provide any of the cold start, stop/start driving functions that the factory ECU's 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 ECU's 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 left over $$$ on other performance enhancing parts.
