Im a beta tester and not 100% certain what I'm allowed to release info-wise, but since pictures etc have been posted I think I'm fine chiming in with this info.
What I can say in regards to people's fear of the pumps burning up super quick - the pump isnt always spinning at max RPM or even at 3/4x the stock fuel rail pressure at all times per given situation. At idle I'm still only seeing 750ish psi rail pressure, not 2300psi so I'd assume much like a transmission the Helix (maybe along with or due to the tuning?) has different "gears" or at least drive speeds it functions at. I've yet to hear of too many HPFP even going out early due to the shotgun setup which I can only assume is intrinsically always spinning faster than the Helix at idle-low rpm due to being driven by the belt which isnt speed adjustable AFAIK and since its driven by a pulley not a gear set, it would have to always be running Yx faster for any given RPM. Really the only time I see the rail pressure go to 3800+ on my base tune is when WOT and the boost target gets significantly high. I currently have a beta unit that is different from the final release one (afaik only one relatively small change between the version I have and production version will be made) and was told that even though they've made a change, they still have plenty of cars that have put significant amounts of miles on this version of the OD, they just want to make the aforementioned minor change to ensure 0 issues at launch instead of a "beta phase 2" on public release like with other products on this platform - I was specifically told by Spool about one that is the same exact version as what I'm running that has been going strong for over 30k miles with no issues, so you won't be changing your pump in 5-10k unless it was already on it's way out and you just got unlucky. I'm running mine on the HPFP that was on the car when I bought it, which is the revised HPFP as far as I can tell but still has at least 65-70k on it.
I've also heard rumors from (likely) beta testers of other rigorous testing being done by Spool that I havent personally confirmed with Spool but if true you *really* shouldn't need to worry about the pumps going out every 6, 12 or 20k miles especially on a new unit.
Other things I feel comfortable saying or confirming: the installation is pretty straight forward, if a bit time consuming for someone like me who had never taken the IM off and had to source some extra tools for install but I was also being very anal about things including how I was routing or re-routing things in my engine bay after the actual Helix was installed rather than just dropping it in willy nilly and testing. I now have a boost or vacuum leak I need to locate and fix, but upon initial install and flashing of the tune everything seemed to be working perfectly, to the point where I had to be careful driving on the street at first and almost re-learn my car due to the clearly giant jump in HP from the one simple part. No need to mess around with installing a PI controller, tweaking the tuning on either the DME or standalone for fueling, and way less parts to install. Just dropped it in and had my mind blown by what I was experiencing even though I had already had high expectations.
the HPFP control isn't simple and I think there's still a bit more work to be done. There's flow control mode, pressure control mode, flow to pressure transition and vice versa, fuel volume model, fuel volume req to amp current req, amp current req to duty cycle, current controller P and I, current adaptations, fuel req PID, and a few more I can't think of off the top of my head.
