Default IFR and Boost Reference Regulator

I have mototron 60's and an aeromotive boost reference fuel pressure regulator (running a 6.0L with vortech)..

what do I exactly need to do to set up my IFR tables correctly in HPtuners? Right now its running SUPER pig rich whenever i get into boost.

Any help would be GREATLY appreciated.

thanks

It would be a table with the 0 vacuum value throughout
(no change w/ vacuum). That value depending on what
you have for real pressure and flow reference pressure.

You probably want to do a similar dressing of the injector
offset table to remove the vacuum dimension there (but
keep voltage). Though offset data is difficult to come by.

Remove the reference hose and measure the rail pressure (58 psi);
note any variations with RPM, and take the average.

Then calculate:

flowrate
= rated_flowrate * sqrt(pressure / rated_pressure)
= 60 lb/hr * sqrt(58 psi / 43.5 psi)
= 69.28 lb/hr

which is as you calculated;

Then use this value flat across the IFR table, as Jimmy said.

Don't forget to reinstall the reference hose.
