I was doing a test pull on a new tune, 1st gear pulled super hard as did 2nd but during 2nd gear the car backfired hard and I let off. It felt like when you blow off an intercooler pipe but it's definitely not that because it did the same thing last pull. This time I logged it on evoscan and my timing seems to go weird and I got 7 counts of knock! What could be causing this? I do have the full evoscan log I can post if you're interested in helping but I'm on my phone rn. In the picture left to right its throttle position,rpm,knock and timing advance
