Hoping I can get some second opinions on how my car is running. This is at 18 psi then falling to 16.

Instead of worrying about wot start tunning fuel trims. Looks to mee like the car is lean.

So the higher the number the leaner it is? AKA the more the ecu has to richen it up?

But he isn't knocking. I'd go as lean as possible til you knock and back up a little. Running pump gas should limit you to around 11.5 a/f max. Which is a good pump a/f.

I get a 1 random count of knock once in a while but I've narrowed it down to phantom knock, something with the lifters.

Yeah it looks good. You could lean it out a little more. If you got a wideband that would really help. I almost learned the hard way!

I do have a wideband. AEM UEGO. It's between 11 and 10 by redline.
