No you were right before, he wants 4 in 6 out. 2 is for a Z32 MAFS.

well 2in 6out everything reads but it idles very rough with high and low throttle at 0. it runs very well at 1in 1out. is there a reason why?? i also just tried 4in 6out and it seems to still idle funny.

aight i got it worked out now with the correct 6in 6out settings with the stock sr maf. but this might be a broad question but does anyone know a good high and low throttle setup. i have 255 walbro fuel pump and stock maf obviously with front mount runnin 12 psi. stock injectors
