I have the SVC intercooler. At first I was a bit concerned that the factory blow off vale now Vents to atmosphere because it's dumping air after the MAF read it. After driving it for a couple weeks now, The truck doesn't seem to mind it at all. In fact the blow off valve doesn't open as much as I thought it might. Maybe that's due to the 10 speed automatic keeping it in boost most of the time while accelerating. compared to my old Subarus which would noticeably run rich between shifts, this raptor seems unaffected.
