May be an obvious question, buuut..

Well worth doing, with this pin I've had to turn the fuel screw down nearly a full turn to clear the smoke at 26/7psi!

Your doing it all wrong then, your not supposed to turn anything down.............ever, too much smoke mean that you need more boost................not less fuel, that is backwards progress

That is usually my philosophy but the wastegate spring must be weak and wont budge past 27psi.... the K04 will be my new boost producer soon though, no wastegate on that
