i kno peeps say you can use the afc hack over 12 psi, if u get and upgraded map sensor like a 2 or 3 bar map, but has anyone here actually done it? and with any other mods? and what were your fuel settings? thanks.

 

well this isn't exactly what you meant... but that kid who made the 300+hp stock d-series did it on the hack (at somthing like 16psi), he used the stock map though. I don't really understand what he did... must have tuned it rich and then crossed his fingers?

 

yes i have when i was using the hack. using the 3 bar map sensor, on the afc adjust the 'sensor input/output'. i think it's like 14 in and 6-8 out. i'm not sure anymore...it's been awhile since i sold mine. but it's something like that. although with the 450s you'll be running kinda rich at idle...but it'll still idle fine if you adjust the fuel pressure via FPR.
