Your right, I like to be at the bottom left edge of the center island. That way when the motor comes up on boost it moves diagonally across the center island. I was just mapping the 60-1 to your combination. It maps out to the upper right of the third island which is over spooling it over 100K. Rule of thumb 70K - 90K it the optimum impeller speed. Bottom line your making too much power for that turbo.
