Stock the gap is about 0.054" or 1.37mm. However, with a blower you need to step it down to avoid misfires. There's no "set" value for blown motors though the generally accepted value is right around where you are now, 0.032" or 0.81mm.

In theory you should run as much gap as you can while avoiding misfires. People's experiences have shown that on mildly-blown apps using stock coils that gap is right around 0.032-0.035".

i think im going to try and gap them again at like .035", to see if it runs any better or makes a difference. Thanks

Why do you think they are wrong? I have seen plugs go bad in a few thousand miles with boosted applications.
