http://www.streetracersonline.com/articles/turbo/boostctrl.phpAs appealing as an electronic interface may be, one should note that an ECU upgrade will typically conflict with a unit like the G-Reddy. You will have to chose which one you preffer. Mind you most ECU upgrades will come with preconfigured selecatable boost levels. In addition, they will also control all other vital engine parts such as fuel and ignition. However, the problem with boost controllers is that your engine was designed for only so much boost pressure. Altering factory settings will yield a shorter engine life. Furthermore, it will more then likely void your waranty. However, some engines have been tuned down. A prime example would be Volkswagens 1.8 turbo. This 20 valve engine was originally designed for Audi. The only difference is a smaller turbocharger and a different intake system.
For this reason, an engine like the volkswagen 1.8T would be an ideal choice to increase boost. None the less, it is still important to realize that overall durability will be compromised
