Default Boost referenced regulator PCM tuning questions....

Would I need to set my IFR table to the same number across the board. Im using a dry kit that spikes my regulator similar to that of a Mustang 5.0 kit.

Im curious that if Im driving around in cruise mode would i set the IFR number to a flat number across the board? or leave it alone and just let the nitrous spike the regulator? TiA...Any help appreciated. I know the PCM is already adjusted for the 42 lbers I have just curious if it would be best in this situation to run it around and allow vaccuum to adjust FP or just leave the PCM like it is.

The IFRs should be constant with a normal vacuum/boost referenced FP regulator. Let the nitrous spike the regulator.

What would be a good constant to use for a FMS 42lb injector...The 42 lb rating is rated on a ford fp system not the 58 psi we LS1'ers have.

I was thinking 48.xx would be a good constant to use.

Also how would it affect my current tune status. Would I need to go in and change my idle qualities in Edit >?

Anyone have a way to change a lb/hr number into g/sec for use in Edit?
