Hi Dave, if your old turbo was the one I remember the reason it spooled good and held higher boost levels was because of the somewhat unusual turbine wheel we use that has extended tips, it also has the largest exducer diameter that will still fit in the T3 housing, in other words it's much more efficient. With as much turbine wheel ("vein") to housing clearance as a typical T3 has it's a wonder they work as well as they do? Anyway if your turbine wheel did have "cut veins" that's not the reason it spooled better, in fact that old fashion procedure actually hurts spool up! The reason it's done is to improve top end performance. In other words it was the unusual turbine wheel that gave you better spool up. As far as adjusting your waste gate it's best to know that your base boost is in the ballpark first of all and then set it for your desired max boost level from there. Shortening the rod will of course increase your boost. Take care, Dave
