right, when i brought my rs i couldnt get it to boost over six psi except in 3rd once when it hit the limit. since then ive fitted a brand new turbo, actuator, pistons, rings, rebore, head reconned, rad etc etc, ive ran her in for over 600 miles and slowly increased the boost, my cars now boosting 15psi but my ecu has never been chipped, and im running the amal valve

weird, any ideas?

also i blew a small hole in the top of my gearbox last night, any ideas what could have caused this too
