Ok this is a simply over lay of a GEN1 stock block running the Borg Warner Ford turbos /BORLA turbos 598TQ @3600 rpm 482HP @5850 rpm .on a 93can tune with the BORLA kit.
these aren’t even meant to be close to the CRP STAGE 4 or stage 5 turbos..close to the stage 3 as the exhaust side is still stock …
so is this simply a case of the CRP tune being detuned/ overly super safe then, as I’m seeing stock raptor/stock 3.5 Ho and base 3.5’s gen2 laying down over 600rwhp on stock turbos, so really it seems like either this is making less power with less boost, or a case of trying to make the same power on less boost maybe which I’ve seen done, which seems to cause less stress on the motor maybe..while also being more consistent due to less heat maybe ? …
