So I have put on my 20g, Tial 38 mm mvs, greddy bov, 3 inch cm maf and a translator. It has the innovate MTX-L wide band and it keeps bouncing between 22.4 and 7.4 afr. Keep on mind that I haven't put in bigger injectors or had a tune yet but I had nochoice but to drive the car for 3 days while fixing my other. The first day I drove it my afrs were around the 14.9-15.4 mark while at idle and I was building 15 psi easy and the car was quick. The next day it won't build over 5 psi most of the time and the afr is either 22.4 or 7.4 no inbetween. I was wondering if the smaller injectors could be at fault? Also the bov is leaking I think so I'm going to replace it with the greddy fz. But I was just wondering if there was any input as to why it would run fine considering what was still needed the first day, but Shit from then on. Nothing had changed. Thanks guys! It also has a 3 inch down pipe with nothing else back because it's being made at a local shop right now.
