Just to report back..
Best way to describe this new setup - Proven on track!
I have now visited this track in the last 2 years >8 times. When I had the stock engine with upgraded turbo and bolt ons (plus higher octane than tuned for) it would still show me a few knock lights, then rebuilt engine with forged stroker kit and the EFR 7163 turbo, it would still show me a few flashes of the slow knock light every lap.
I then went with this direct port meth kit, it madea sh!t ton more power, made it much more consistent lap after lap and not once have I seen a knock light again, ohh I'm running even more boost now (2.0bar for track).
Here is the lastest video of me @ Sepang F1 track in Malaysia (yes I'm still learning and have a long way to go) I actually blew my rear diff on this trip boo:
