I went up for the first time this year thinking I had cured my fuel issues from last year with a new inline pump and FPR. After taking it out at 8.5 psi, I am still seeing 12.7-13 AFR at WOT. I then went to adjust my blow off valve and kept the hood off during testing. I took it out and started getting cruise AFR in the 9's which had never happened before. I then took it out for a blast with the same boost and saw AFR's in the 11.5-11.8 range WOT. I then put my hood back on and my WOT AFR's went right back to the upper 12's to 13. I am at a loss as to why the AFR's would be drastically lower with the hood off rather than with the hood on. Does anyone have any thoughts on this? Ultimately I am thinking I will need to upgrade to PCV-PTI with 430cc injectors but I am still confused why it ran so well with the hood off and why the numbers were so different.
