Essentially I interpreted that XDI was saying you can run a higher(3200) PSI but they don't recommend it for consistency on for a street car. I'm assuming due to stuttering perhaps. I know FIC has this issue above 2600psi.
Did your experience find something different?

Higher pressure equals less flow through the HPFP (or any pump for that matter). So, it depends on your fueling needs. You’ll have to datalog and adjust as needed. If your IPW is getting much over 6.0ms, then try tweaking up the HPFP pressure but you’ll have to keep a close eye on it…when rail drops off it can be fast. LPE recommends 2175 because that is max flow, but you can run higher pressure if needed.
