tire pressure is good, my exhaust smell is actually worst off now. my whole driveway smells like a gas station when i start it up lol. i thought oversquare allows for lower friction losses?! one reason why maybe my BSFC sweetspot is wide from 1500-4000rpm at %80+ load? i think this has more due to do with the all-wheel drive and slightly large fuel pump and 500c injectors. also from what i have read the AVLS system is almost 90% of the time in high lift mode. and as for heat as i said i never see it go below 88'c wether at idle or highway cruising. i'm sure this engine just doesn't like gas asdditives, i mean i had no problems getting 33mpg in summer highway, now when i cruise it just doesn't go above 27mpg. reminds of running e85 vs pure gasoline in fuelflex cars. i think maybe my expectations are too high...
