I cranked up the boost to 12-13 psi today and noticed that the AFR drops to 11.0-11.2
Is it normal or should I worry about something, 11.0 is probably not bad but I was expecting 11.5 up to redline
I've only done a few pulls, will the ECU correct itself to 11.5 after a few moments?
*I have an AEM wideband btw
I was wondering if I should be contacting Ben at JWT, thought I could ask here before..
Thanks guys

AFR is very dependent on other things too, such as fuel pressure. The ECU is seeing more air moving therefore increasing fuel output to meet demand, it's not always going to be dead spot on perfect. I make very minor adjustments to my fuel pressure to fine tune for AFR like that.
