Hi, I've got tuning software for my cars. I've logged the pressures, and the boost is limited to about 5.5psi. A bit more when it's very hot intake temps. It is limited from about 2000rpm. My tune is about 7.5 psi, and I'm on LPG. I can tune it for max horsepower, but its our daily drive, so the tune is safe, and is very drivable, and I get about 1L/100 less fuel use than stock, and more hp. Makes me very happy. If anyone is interested in a tune, and are in Melbourne, I can help. Nathan
