I want to run about 7 psi on my stock d16 motor and i still wounder if an AFC hack work better or a FMU witch is best to use some one told me that AFC hack doesn't work for motor run less then 9 psi but the FMU will all way run rich ... so witch way to go any ideal ? and how much boost can my motor take ? thank you

 

Just read the forums because there is a lot of info about the afc hack and fmu. The fmu will be fine for running 7 psi, but if you want to go any higher I would get the afc hack.

 

just get the afc regardless of how low of psi your run. youll regret getting that fmu later on.

 

Why would i regret ? also im looking to do an ls swap later on so the AFC would be best ? because ill turbo the ls also but if i have an FMU and AFC will that be best ? because im in low buget now but i wanna boost my D16 ... if i was going to buy a FMU what type is best to use ? the 12:1 or 6:1 ect thank you for your reply
