Basically, I treat it like an aircraft engine. Rich of peak for climbing and decending (TOT around 810C) then lean at altitude when the MAP is lower (around 870C). Peak TOT is around 915C.

a set of the NEW ones 0.500" from a friend - highly recommended.
Mazda increased the size of those bolts for a reason and my original set were all spiraled with silicone ... put a little silicone on the 0.50"= as

Dave,

Run a spiral of RTV around the body of those tension bolts next time you remove them.=C2=A0 That will pretty much eliminate the vibration breakage.= =C2=A0 Don't
put it on the threads.
