KR Is going to happen on a stock 04+ with a 3.4 pulley no matter what your fuel trims and operating temps are. I would imagine you'd be getting KR at WOT at any speed and quite a bit of it. It's not going to throw a code until its too late. You need a scanner or aeroforce to monitor KR. If you're KR free with nothing but a CAI with a 3.4 on an 04+ I'd be beyond shocked. Like spotting raptor jesus fighting the flying spaghetti monster type shocked.

Go back to a 3.8 pulley until you get some mods, and don't go WOT until you do go back.

Okay thank you
