Is some KR normal? So I had some bad KR in the past on my 5.3 swap, fuel trims looked bad. I figured it was the pump, i was just using a low pressure airtex.
I upgraded the fuel pump to a walbro 255 inline, and new lines. Basically I am just wondering if someone can take a look at this short pull and tell me if things look to be in line or if 2deg of KR is an indication something is wrong.
I have eliminated every possible fuel issue I can think of, so I guess Im stumped.
attached is the log.
Thanks for any info!!!

Your fuel trims are quite a bit off still it seems. As far as the stock knock sensors being too sensitive, not sure about that.
If you posted your tune, we could look at that also and check it out, or you can email it to me for a free evaluation. Email link in the sig!

When you say they are off, how bad off are they? Before I did the pump swap they were spiking up to 50-60%, when I saw a max of I think 10% on this log I thought that was within an acceptable range?
