hi i am currently running the vafc hack plus i am using an inline fuel pump. do u think this will make the car run too rich. i am feeling some hesitation past 5500 rpms at wot. do u think the pump is making the injectors dump to much gas at wot. thanks

 

i've heard that the hole reason that the afc hack is great is because all you haev to do is upgrade the injectors, it gets rid of all the extra (and upgraded) fuel pumps, fmus, etc.

you are probably running very rich, that is why you are feeling the hesitation.

 

yeah thats what i thought im going to remove it and see how it feels thanks

 

It also could be that you are running lean. Do you have a EGT gauge? Even an a/f will help.

i dont think im running lean. i pulled the plugs to change them and they looked like the car was running really rich. the plug was black and looked fouled

 

why not just lower your settings on your afc. set it to like -36 or -37. i found that with a wideband at -35 i run 11.4 afr
