Anyone have any luck running more than .035 plug gap?

[6SENSE]

Recently had an issue when I tightened gap from .035" to .032" and lost a couple mph in the 1/4. No matter what I did I could not get mph back to where it had just recently been. I have been told that you want as much spark exposed to the mixture as possible without blowing it out due to high boost+poor ignition. I apparently had plenty of spark with .035 and hid the spark by tightening which I am told is considered by some to be a sort of ignition retard. This made sense..........so hense the question, if a big gap is a good thing then has anyone tried anything larger than .035? How about .040"? Wasnt stock gap on '84/85's .060"? So we are waaay below that anyway. If I had no problem with 23psi boost w/ .035 maybe I should see if I could get away with .040".

Any thoughts?

Nah,stock turbo car gap is .035".

The ONLY reason to close up your gap is if you are experiencing ignition breakup at higher boost/rpm.If you car runs good at .035",leave it.

Hell,if your car is firing fine at .035",turn up the boost.

I had a problem with a miss and found that the gap on one of my plugs was at .040". I tightened it to .035" and double checked the rest and have not had a problem since. This miss was experienced at 13psi. Going any larger on the gap has not worked well for me.
