because your good AFR's are in the fully loaded regions of the map - spool and shift regions probably need to be leaned out a bit...

 

I sorta experienced this as well yesterday. Was hard on it and there was a burning smell in the cabin, smelled a bit like burning oil? And when i stopped the car i could see a bit of smoke coming from the hood scoop. Popped the hood and there was some smoke coming up from behind the engine from beneath the heat shield... is that normal?

 

id have to say smoking comming from any engine wouldnt be normal lol
