what are your current fuel trims? Are fuel trims turned off for WOT operation?

Have you logged fuel trim in use during WOT?

2008 @ 39,500 It's definitely concerning, especially because it pegs 13:1 at WOT lol

Anybody know if a drop in DW65c constitutes a retune? MAP has a 10% sale that ends today!

It would increase FP possibly, making the AF mix richer. Shouldn't be a problem IMO. Just watch the AF, to make sure it's reasonable but I doubt you'll see much of a change at all.

Just an update. I replaced the fuel sock, cleaned out the pump housing and just started running injector cleaner which nearly fixed the issue. I'm going to run a full tank of it then run another set of logs. But take a look at the difference.
