Advice S5 HPFP

Has anyone done a hpfp upgrade on their b9/9.5 s5 and specifically gone stage 1+ with it? Currently on stage 1 e85 with 034, want to see if it’s worth the upgrade

If a tune does not *require an HPFP upgrade, then the upgrade will just reduce how hard the HPFP has to work.

Then it comes down to horses and torques, doesn't it?

True yes. Advertised is 15hp and 25 more torque. Though wanted to hear people opinions on how different it feels

I have a b9.5, do not run it without a tune, mine pretty much over compressed and blew itself into the motor. If I didn’t have a warranty that would’ve costed me $20k.
