I suppose it would be helpful to provide some info for you, right?

Here is what I've already tried
Only run cheveron 91 (or shell if I have to, never anything else)
NGK 1 step colder plugs, gapped 0.034 and 0.040
NGK 4306 gapped 0.034 and 0.040 (less than 500 miles on these plugs)
Boost leak tested
replaced the cracked manifold
exhaust leak checked
brand new valves, guides and seals
put the PCV on a vented catch can (was on a catch can with a check valve)
did several cleanings using mopar ccc
been running 50/50 meth for a few months now
coil was replaced less than 1 year ago
plug wires are less than 1 year old
added heat shielding where I could
injectors are less than a year old, but I'll give that test a try. I've been wondering how to test which cylinder(s) are knocking thinking maybe 1 or two of them are leaning out, but how could that be with meth?
replaced knock sensor
I know I've done more, just cant think of anything else.
