Hey everyone , just wondering what is the ideal WOT and not too Lean mix to shoot for is it around High 11s to 12 s ? Is that where it should be ?

Depends on the car/ tuner. I've seen from low 10s, to high 11s, in some 10s cars. Right now, while at 18 PSI, I'm running ~12.5:1.

Like Bruce says, it depends. You could easily get in trouble if you try to tune to a specific A/F ratio. Tune for best performance, with no knock. THEN look and see what the A/F ratio is, and what the EGTs are. After you have tuned using performance as your yardstick, then you can use A/F and/or EGT as a reference to help keep things at their peak. BUT-- if you change cam, injectors, turbo- then you have to start over.

Safe zone is 11.5 - 12.3
