the probe gt wont boost past 8lbs, on the stock ecu. unless you get a standalone, or get the chipped ecu. Ther used to be a guy that sold them, but he doesnt anymore, google Zombie Chip Probe GT. It was the best thing for the probe turbos! Im sure someone has figured out a way or started to make a chip for it, but i havent been on the probe forums in years!
