I use a TR6 gapped at around .027. They work great and are cheap and plentiful.

A TR6 Is a projected tip also, it's the plug design not the tip material that determine projected or non projected. A TR6 equivalent that is non projected is a BR6EF.

I have a set of those I am about to swap. What would you get them at for a mp112 on a LS6 making 6 or 7 PSI?

For that boost I would run them at .032 which should be what they are gapped at out of the box. Naturally I would check them.

Why run a non resistor plug in a LS? Many have had issues with this. Also a 8 heat range is too cold for his boost level.

People always say that but i have never seen a post/thread/anything. Not doubting you but seems like 1 guy 10 years ago had an issue and that idea just kinda took hold.

Even say that's a non issue, a 8 heat range is way too cold for that.
