Hey guys. Just wanted to see if you could point me in the right direction on this. Partial throttle onward the car runs horrible lean, like 15+. Idles at stoich and when you blip the throttle it goes right to lean. Mod list
Catless down pipe
Walbro 255 ( swapped in stock pump to test..no change)
Cobb ots vf39 map for Cobb short ram intake
V3 access port
Sti top mount
I've cleaned the maf sensor and swapped pumps. Idc is only at about 65% at wot. Maf volts are around 4 at wot. Boost fine but bogs and you can feel it running hard and afr drops to 15+. Obviously it's bad so I'm taking it very easy but a little direction would be nice. Thanks guys.
