Hello dude, Well i tune cars for a living, so here goes....... You ran the car on a dyno dynamics dyno right? In general terms, yes the afr is a little on the lean side. I've seen starlets/glazas before running stock with an afr of 12, but thats at 0.6 bar. At a bar of boost i would be much more comfortable with an afr of 11.5 or so. This will give a lot more saftey in the tune and wont sacrifice that much power. The 15 afr at the start is toooo lean though, for sure. Unless i am mistaken, your stock base fuel pressure (pressure with the vac line not connected to the reg) should be 3 ba
