If you go on YouTube all the 2.0 vauxhall turbo engines that don't fall apart use MegaSquirt to replace the ECU. But you have to take a hit of a least 400 squid to make it work well. The system looks pretty good (electronics engineers view) and they have auto tune software for your laptop. Pushing the standard ECU is possible but the price of not quite getting it right is far higher than going with a MegaSquirt system, also remember electronic computers (i.e.the ECU) don't last forever and will eventually fail so if your going to upgrade, better with a newly manufactured one.
