quick AFR question

[dsmotors95]

my afr's at idle are around 13.7, is that bad for the car and am i loosing power if im running a little rich all the time? im on stock boost if that makes a difference.
thanks in advance.

Yea your idle should be around 15.5-16. Do you have a way to tune?

So after looking at your profile you have no way to tune and you are running 550cc injectors. Got the wally too. Theres your problem. Also you should put what turbo you are running in your profile.

Only if you want a lean idle and hotter exhaust gas. I'd sooner shoot for stoich.
