I know right I run 1200cc of 100% meth and my timing is no way near that advance in the early cells (140-180).

I still have yet to do a leak test but unless there is so odd ball place where the car could be leaking I am doubting that it is from the hoses. They are nice and tight now. Any help will be greatly appreciated I am at a loss.

What will boost leaking have to do with knock?

Like it was mentioned above, too much spark advance, set the map to the timing the ecu pulled it to in order to stabilize increasing counts, but it looks like your on the right track now anyways

timing was too high in certain shared load cells. fuel map needs some work, but I can fix that if you want.

Wouldn't a boost leak cause it to run richer?

That timing map looks very specific to one tuner. I wonder how his timing maps look for Porsche and 335i's if thats how something other than his baseflash looks.
