I'll look into it. I've got a SS ceramic coated Plog, ported rear mani, and a 3" R/T downpipe. Everything was on the car when I got it except for the Plog, which I installed myself. I'll make sure everything is tight and get back to you.
I did flash a 2000 bin file to the car and I did a scan earlier and didn't notice LTFTs going rich.
