What I noticed was a difference in IFR values, though minimal, they are different.
So my question is. If flow rates are determined by fuel pressure and rated flow, why would these be different through GM cals? Could it be that this was part of GM's detuning of the F-Body to keep HP down from the near identical LS1 in the Vette? Could this actually skew the figures of IFR spreadsheets out there? ...
