I can’t adjust the A/F at idle to keep it at 14.X to 15.X

Vacuum while you're running lean: 13 to 15 vacuum at idle

Could be an exhaust leak: I'll check the next week

What's your low load fuel map look like: 0

But I change in low load and the engine respond feels better:

400 Rps: +10%
800 Rps: +8%
1200Rps: +7%
1400Rps: +6%

Sensor Monitor screens on the pro and check the CF (correction factor):
O2: unplugged
CF = 0
VF = 0

By the way, in first gear the engine fail from 4500rps when the car is running (I don’t know how to explain in English :icon_redf), in the other gears don’t have that problem.
