You don't want fuel pressure drops, even momentarily, below 1500 psi... but that's really up to your tuner and how comfortable he is with your car...

RGR that,  AJP has not made a concern of it so i called it good. but it is good to learn as much as i can.

Since my fuel pressure is fine at 75ish ambient,
what does that say about the fuel system? The answer I'm looking for is how far off am I from a model tuned sho? My thinking is if im within 10% of a model tuned sho then there is nothing broken its just lazy and I can confidently grab the LMS pump and get those gainz lol. IIRC something like 40 hp is a nice bump.

wait ... is someone claiming a 40hp gain from a HPFP?  As in your tuned to the hilt alreasdy, then get a new pump and gain 40 MORE hp?

dont quote me but maybe stealblue said that it has similar gains to spraying meth? again I'm​ kinda guessing.

No, LMS has not released ANY information on the tuning of the new HPFP they are developing. They have said they will release information when the pump is available...

I have been on this like white on rice...

rgr that..

I know for sure you can't run corn without further modifications. No info on what that would be. I'm sure they will try hard to give us a good bang for the buck as most of the community doesn't have meth + lms hpfp + rebuilt turbos etc.

I have never made that claim. What I have said is that when I spoke to Dave at LMS about their Alky Meth Kit a couple weeks ago he mentioned it might be worth while to wait for the HPFP. He stated that the biggest advantage to their meth setup is offsetting the stock HPFPs limited ability to maintain fuel pressure after tuning.

The new HPFP is supposed to assist with that issue.

No tuning information or gains have been released from LMS or Mustang RTR about the new pumps coming out.

FoMoCo has a tune from AJP that can run E85 I believe..

Here is the thing right... if you really want to know, call LMS. I have called several times to talk to them about various setups and gear. Ethan, Anthony, Dave, and Matt are the guys I have spoken too and they have always been very upfront and informative. My guess is the more people that call, the more pressure for them to release stuff... aka... the sooner they can start getting a return on the dev costs for their stuff...

Seeing some pretty high boost spikes 17 psi which do get me down to around 1500 psi but it recovers pretty much instantly.

Yup. Trying some new fun stuff with e45 as well.

Still looking for how much fuel I'm "missing". If the rail fuel volume is maxed out right now @ 13 psi of boost and 80f ambient where am I compared to another SHO?

Welll... with LMS 4+X Race Tune I have 1900+ at the rail with ambients at freezing....

Dunno if that helps?

Not sure how much more demanding the 4X tune is but seems to me like my car is somewhere under 15% off of yours. I think It's close enough not to worry about the pump not helping.
