Be real carefull when gapping them as they are easy to damage the electrode.

did you upgrade your ignition system? i would almost expect blow out at your level of boost pressure with that huge gap

general consensus is to not use platinums on FI cuz you have higher chance of blowout due to the fact that the tip surfaces of a platinum spark plug is not large enough to make a good conductor in a rich, super high compression environment.

Binder --> random misfires? thats what im getting and im due for smog check soon. was wondering if a change in sparkplugs would help the cel go away.

not the CEL for random misfires. It was spark blowout but it didn't trip a code.
check out your plugs to see if they are worn or the gap is really large. it doesn't sound like the same issue though.
