I ended up running 1/4 can of Boostane Professional in each tank to get clean timing and avoid knock. Not sure if you could get away with it there since it's technically not for road use.
Have you pulled your plugs to check if you get the orange residue from boostane? That's what I don't want to have all over my powertrain. There used to be a well known bimmerpost member "teh boost" with a Cali tuned M2 who chased good timings and used boostane. His plugs, downpipe, exhaust were all coated with orange gunk
