@ June, your EGT's a good now. Don't worry too much. But remember, Higher boost = lower EGT's but there is a point where the higher boost becomes useless. Like cruising at 100k's. Your over working the turbo for nothing.
Not to go against TD the almighty. But if you set the boost at 10psi, it will be 10psi period. With the dawes there is only one point you can set it at. Thats why the needle valve comes into play. Kinda.
