Here's my set up.
SP67 Budget(stock fuel/stock MAF)
FPD bypass
3-row
exhaust/intake cam-gears
downpipe/cat-back
AVC-R
SAFC2
First, I leave my boost controller off. The WG with the budget kit keeps the boost right around 15-17psi. On 93 octane my wideband starts to read in the low-high 12's. My SAFC is completely decked out (50%). Is this normal to read this lean at this low of boost? Do I just need a fuel system? Is this a sign my factory fuel pump is going out? Also, my FP only reads 39-40PSI at idle but it goes up to 60PSI at WOT. Any help would be appreciated.
