g2871r, z32 maf, 800cc top feed and aftermarket intake manifoild.
so the prob is when change the injectors and maf sensor in nistune the car runs perfect when it's under load i can go for drag racing(12,5 afr), but the car doesn't run at all on low rpm and it's inposible to cruise. the afr is about 28 and the car is deaing i have to hit the gas to keep it runing.
and when i drage the k konstant to have idile around 14.7 then the car goes in reach under load about 9.8 ~ 10.. AFR
