Eventually got it to the dyno only to be told its not boosting at all. actually it was , the inlet pressure was atmospheric instead of vacume.turned out that the wastegate was siezed open and the tubby wasnt getting enough gas to spool properly. long story short,a new watsgeate was sourced, the welder came out and im now wearing a turbosport ultagate 38 jobbie. looks ok ,fits nice and hopefully ill have it pumbed in over xmas. still need a screamer pipe and some vacume tubing too.
getting there slowly..................
