Funny this should come up. I just went back to the 55's from the tr-6's for a quick test. I was having a few * of KR at around 5K rpm's with the tr-6's and now with the 55's it has shifted to around 6K and only 1-2* for just a blip. Do you think the meth has anything to do with it?

 

Aweeee crap! Everything seems to be not working lately.
First my Suspension parts, then the meth, now the plugs.
I'm going to give up here pretty soon.

I am running TR55's at .035 gap and all seems well here..
