vacuum multi question

[srtpapa]

I'm new to hp tuners and I have been chasing a few things on the car tune wise and I think I stumbled across one fix. (car is a srt 4) I have added a return line with a boost reference regulator. vacuum line has been ran to the regulator from the intercooler pipe for raising rate. under the fueling tab and open/loop base there is a tab that says vacuum multi. is this the tab where I "1.00" out the table for a boost reference set up? thanks in advance!!

I would also assume the power enrichment table will need modified as well

Search for this topic. there was a thread where this was discussed for this application and some files were shared including the Mopar Stage package files with the boost referenced fpr.

It's more complicated than it seems as first blush as the vacuum/pressure is the difference across the injector tip, not just the manifold pressure.
