at 100% in 4th gear 10psi boost my car goes 16 15 maybe 14.7 to one air fuel between 2k and 4k rpm with no correction on the afc soon as it hits 4k its 9 8 to 1 rich so i had fuel with the afc to be save and i have to add like 30% until 4k then take out like 10 % to get it to run like 11.2 10.8 is area under boost across the board with it richin up a bit at 5500 so i couldnt figure it out
so i screw the afpr all the way in can not get more than 40psi out my 255 pump and its starts to scream so today i change it out for a stock toyota pump i can get 50psi out of it the car is still doing the same thing on the air fuel ratios just now i only have to add 15% of fuel until 4k and still pull about 10% out to get my desired ratios i checked the bladder in the afpr to see it was tore it was not so i cant understand why its doing this even if screw the lex in its still lean until 4k and then its super phat anybody have any suggestions ideas?
