Yes. IPW would remain the same. I would lower it even more and not run SOI any higher than 370. With your EOI where it is, there no reason to back up SOI so much.

Basically at 392, you're injecting with 32 degrees of crank rotation left (32 degree before TDC) in the exhaust stroke and starting to spray fuel out of the exhaust valve.
