i actually have a similar question regarding afr. i have a 2.8 pully and a fairly mild tune, when i go wot my afr comes down to like a 10.9-11.1 which i know is rich but its a safe tune bc i dont have cooling mods yet.
but when i go like 50-80% throttle and like 8-13psi my afr stays around 13.8 14.2 am i running to lean at non wot or is it ok bc im not makeing full power?

btw i have a 3.2 pulley on stock injectors with a tune (w/ 3 in intake and full exhaust)
could this cause my car to go into limp mode?

stock injectors are pretty much maxed on stock pulley. you could simply just not be flowing enough fuel
yea i thought about that as well, before i tried this set up i talked with a few people who ran/tuned for this set up before and said they had good luck with it, maybe my tune isnt up to par, idk i do have some dtcs ill post up after i run to the store to scan em

ACESSbalt - It's the tune man, even if the injectors are maxed you should still be seeing the correct afr down low. Is your maf dialed in? Are you running a maf only tune or ve only tune or a blend of both? Are you going into PE mode? Whats your PE Enable tps set at? If you need some tuning help let me know.
I would lower your PE enable tps, if you are 80% full throttle and not in PE then it's set to high in my opinion, especially for modded people.

If possible you need to get a log of the car. Chances are you are maxing the injectors, but you shouldn't be maxing them until over 5K RPM. Under that the AFR should be fine. If it is lean all the time then your tune is definitatly out of whack. I don't suppose you have any way of putting up the tune so it can be looked at...
