Put the 150 tune back in the car last night which uses the resistor mod and went to test it out. With 7* pulled out it went to 4* kr @ WOT and started to slowly work its way down to 1* kr before i let off.

Last year at this time when i first sprayed it with this tune and the same type plug (TR6) it had 0 knock, but i had 9* pulled out then and not 7*. Where should i go from here?
TR7 plugs, if so what gap and how much timing should i pull?
Keep the TR6's and go back to 9*?

You tell us how much timing you are pulling, we also need to know what your peak timing is on the bottle.

Peak timing is 21.5

I've got the data log of the pull if anyone would like to take a gander. Let me know if you would like to know anything else.

I'll have to make a pull this wk, pull over right after and check the plug. I'll let you know what the a/f is also once we get it done.
