Default HPFP Data Logs
Right now in my 2013 Mazdaspeed 3, I'm running a Corksport induction system (same MAF size as stock) and a cobb stage 1+ tune. I wanted to check my HPFP's psi through peak boost, and I read on cobbs webpage to do a 2k-6k rpm WOT 3rd gear pull. I did multiple logs and my psi stayed above 1600. I recently logged a WOT 2k-6k rpm 2nd gear pull and saw my fuel pressure dropped to 1450 psi (I then went back and did a 3rd gear log and everything seemed peachy). Should this 2nd gear pull be a cause for concern or is it normal because it's a lower gear?

I've read a lot of threads that Gen2's can't do ANY mods or tune without upgrading the HPFP first.

That's not entirely true. I'm sure there are many that have done atleast an intake without issues. Gen 2s are just much less friendly than the gen 1.
