If ur gonna use the AFC without any "addons" then your gonna limit your adjustability to just tricking the ECU out of seeing boost(u could prob achieve the same result with a $2 potentiometer from jaycar) & just hoping the larger injectors line up well with the stock fueling maps.

also the faster u spool onto full boost the quicker your gonna find out where the limitation is in dealing with the stock timing,unless u just adjust your driving style to avoiding those parts of the timing maps,u'll prob have to dial like 8deg off the dizzy to get around it,not pretty.

btw not flaming u dude,just want to see u get some decent results,if u dont like my opinions,just ignore them,problem with boost is it goes pop real quick when u get it wrong,maybe if u backed down your expectations on the boost limit,u'll get something going half decent.
