Super happy with the 62/71/13 over a 75/96/1.15. 95 12v, quick rate 12mm pump, 5x16 injectors. However, like all of us i get a little bored. I make right at 70psi and have tuned and tuned. I can move the boost around from turbo to turbo but max i only get 25psi from the primary and right at 70psi total. So here is my question. If i were to swap from the 75 to and 80mm while changing nothing on the exhaust side. I should have very similiar spool with noticeable amount more pull up top? Right? Anybody ever done this change? Worth my time? Again the truck runs super. I would just like a little more primary boost but if i cant get that might as well move more air at a lower psi.
