Your iac is alil high . I would open up the throttle blade alil bit at a time while watching your iac numbers fall to around 15-20ish . Then rest your Tps back to .40-.46

Thinks what about rpms

What about the RPMs? The ecm controls your idle rpm so after you adjust your iac and then your tps you should be idling around 800-850ish or whatever your chip is asking for .

And you would want to do these adjustments when the engine is up to temp FYI

Thanks again

MAF is high as well should be about 7ish. Also, as mentioned wait until car is fully warmed, oil psi has dropped and fan and t stat have cycled a few times.
