This guy was on caltex which is probably the cause for most of his knock. I was getting -2 around the 3600rpm/0.7 range. Both areas are in closed loop, so I reduced the minimum I could from those areas, keeping the whole map smooth. Both cars with same headers and stock exhaust, just driven differently. I didn't get any IAM drop, he did.

I figured dropping timing from that cruise area is a small price to pay for better guaranteed IAM under load.
I tried to keep as much timing in 0.8 as possible as it's already pretty low, I dropped more from 0.7 so it doesn't ramp up there as aggressively.
Here's the diff from v33-v44.
