R33 Missing After Highway Driving....

[MBS206]

it doesn't miss until I jump on it but...

I've got standard NGK plugs with a 0.8 gap

I've only got the stock boost gauge atm and it was sitting about halfway between the 3.5 and 7 mark...

Turned it down so that it sits just on the 3.5 mark.... it has helped a bit, but I can still hear it missing occasionally.

I have found that once it starts to miss if I turn it off and let it cool down a bit the problem goes away for a while until it gets warm again...

You still haven't answered what plugs you have.

BPR6-11ES? BKR8-ES blah blah blah...

What type of plug are you running, what is its part number?
