For everyone here I would say do a return line before swapping out any injectors. Return lines are cheap, easy to install and allow for a great increase in flow and pressure control.
-32% or whatever you pull fuel wise will match pull timing because that's what SAFC's do. Was never an issue and as a matter of fact I sold the MAPCLAMP I had (brand new in box) because I never needed to use it the SAFCII did a perfect job as long as the car doesnt have any BC seloinds hooked up there is no way for the car to contol anything. My FPR is hooked into the Vac system (aka TB) but I found a new vacume distribution block that just came out, basically you would hook one line from the TB into the block then have 6 vac ports for BOV, FPR's, BC etc and threaded seal plugs for the unsed ports..looks hella clean and allows for equal distrabution of the vacume system without cuts in a parallel line. $48 bucks BTW...
Sorry I have not been able to respond to alot of your questions, I am leaving for Ranger School on the 25th and have been very busy. Brad at Hahn RaceCraft is a great guy and will talk your ears off about any questions you can throw at him (but be forewarned he is partial to the port fueler system.) I got my setup before the PF was launched so he doesnt ragg me to much. Good luck guys and I want to see a 460WHP Dyno sheet from someone real soon
