Now that my D66 turbo is installed, I'm noticing a very pronounced amount of flutter of the boost gauge.
With the old turbo, the most boost I ever saw was in the 24-26 psi range with maybe a + 2 psi gauge flutter.
Now with the D66 installed, in a medium level chip setting, I'm seeing about 30 psi of boost, but now the flutter is more pronounced at +4 psi.
Does anybody know what causes the gauge flutter? Is it an indication of compressor stall, intake restriction, greater turbo output or ???
