actually i removed hood insulation pad because it increase my intake temp and because my engine gets hot. in about 5min my car reaches 70'c coolant temp, which is what subaru claims to be fully warm engine. 7-10min until the highest 88'c temp. so im not sure if heat is an issue here.

my afr map is fuel friendly 16:1 cruising under 55mph and 14.7:1 idle. i get 0.23gph according to SG2 warm idle. cold idle 0.6gph. under no circumstances afr goes under 14:1 unless over 4000rpm. throttle response seems excellent. my only issue is as though the gas is evaporating in there. i had to calibrate my sg2 to +10% as it was showing consumption to be too low! its usually around +3% in summer.

forgot to add that my car has a1200rpm closed loop cold start as well.
