TS the regulator on my 6.0 in the J Truck has a vacuum line and drops to 50 psi at idle it was that way when I pulled it out of the van, nothing on that motor had been touched other than it had routine oil changes, it was perfect where it mattered.

Interesting, what year was the donor? One of the fuel rail mounted regulators then?
BTW, the FPR blocks are a reality now, I just need to assemble the inner spigots into the main blocks. They're a 'round tuit, the Blanc-oh's projects are more pressing.

It's a Bronco, If it ain't broke, your supposed to fix it till it is.

That's my motto!
Siemens Deka 60 lb/hr injectors (what Brian and I run) are well known in the Porsche world among other places for being extremely responsive and for metering accurately at low flow levels (think idling around town). They are also extremely loud, but that's a separate issue.
In our Ford application with EEC-IV computers, unless the tune is set otherwise, fuel pressure with vacuum disconnected from the fuel pressure regulator should be about 40 psi. Connected at idle and especially on overrun- think coasting downhill in a low gear, off throttle, engine revving- should drop to 30 psi. When I tap the throttle on mine, fuel pressure response is instant.
I know Thom had issues with Autometer electric fuel pressure gauges, but mine has been as accurate as the mechanical gauges I've used for comparison. I have had a pressure transducer fail, but it was obvious and replacing it solved the problem.

Oh yeah, an old friend of mine used to race karts and he had all sorts of tricks. The racing stripes on his helmet were painted on at a very small angle. He always used REALLY long zip-ties to hold on his rear number plate, and never trimmed them. He used a tiny bit of Castor oil in his pre-mix. Anything to distract the guy behind him and make the guy lose focus, if only for a second. FWIW he hauled his kart around in a '60 2 door Ranch Wagon with a transplantsed 460 for power. It got the same mileage as the 223ci six it replaced, but had a whole bunch more power!
The '73's '04 Scabalanche donor doesn't have the regulator on the engine, but I *think* that I knew at one time that the engine in the J-Truck did have it.

Nothing to do with racing but when I was in tech school we got the wild idea to put diesel fuel in the windshield washer pump and plumb it to the exhaust. Made a classic 007 cloud of smoke at first but when the engine warmed up lost the effect. Probably lucky we didn’t burn the car up!In a different life when I was doing a lot of street racing, I left the exhaust valve seal off #1. Made the engine smoky, made the competition confident
I would crap a lead brick were the gas prices that high here. Just saying that $5/gallon would certainly encourage a move to a cheaper place with better prices. We’re running from $2.85 to $3.18/gallon.

Couple weeks back I paid over $5.30/gal.
Thanks Gov Inslee & our legislators... it's just another tax... on another tax, on top of the federal gas tax. Gas went up 20% in ONE day-seriously, one day!
Also means my natural gas for my house and shop went up 20%. My electricity by the end of next year will also be up 19%. Carbon tax

Whats diesel running up there? We’re in the upper 4$ range here less than your gas.

OK... TOTALLY frustrated.
Fought Ford for 10 months. Built my engine with the donated pistons they supplied.
Been trying to get my tuner to at least look at my datalogs so he can see what's going on.
He replied today (after a full month) and said and here's his quote in my pic below:
WTH do I do now?
3 realistic options maybe- -
1- trying a friends tune who has 56 less ci but the same ignition timing system? See if my afr #'s come down a little. Under hard acceleration my wide band afr #'s are 14.7-15.3 which are WAY too high for acceleration, way high. Dangerous high from little I know.
2- try to learn how to tune with RTTuner so I can potentially blow up my engine
3- buy ProM but they build the harnesses one at a time and are 6+ weeks out.
This means after joyfully celebrating getting my engine together and running that I might be risking a HECK of a lot by going to the beach for the RdUp in 3 weeks w/o a tune and now I can't really drive my Bronco without risk
I like ProM because it is Mass Air, not Speed Density like ProFlow, all the Holley's and all the other wannabe's in the efi game.

I can’t comment on any details about any of the tuners, but I don’t discount the ability of one type of system control or the other between speed density and mass air.
Only when it comes to Ford factory offerings, does that seem to make much difference in a performance kind of way.
Speed density is still a legitimate way to run a system, when it’s an aftermarket setup that can pretty much accept any modifications and tuning that you care to add.
A shortcoming of the factory setup, but not so much in the aftermarket.
At least that’s the way I understand it. I’m sure others with more tuning experience (maybe even you?) can say one is actually still better than the other.

On my 427 I built I bought a Haltech ECU from a local dealer. He was able to give me a really good conservative initial tune for the ECU. Then you can self tune and dial the rest yourself. I highly recommend this route as it really helped me. The name was Chapman performance here in WI. I am sure there are many other.
The 408 I built I used a Holley Terminator X which worked really good also. They had a catalog base tune that was plenty conservative but also worked good. I would have used it on my Coyote if it would have supported the 6R80. I really would not get all caught up in MAF system. We have an older Pro M on my brothers trans am and it works fine but nothing awesome. Almost all higher performance people are tuning without MAF and doing it well. Whichever you choose check out there software and use one which you feel good about tuning on the software. It is quite a fun journey and not very difficult.

Biggest concern for me comparing SD and MA is elevation changes. I can drive from my house just taking my wife for a drive and see 7,00ft difference in elvation in 20-30 min.
I hear stories about guys trailering from sea level to Moab (only 4Kft) and having EFI "learning issues" for several days then it's good. I'm sure when they get home they go thru the same thing.
Is this still common??
If Holley Terminator didn't have this issue and were available I'd go this route... yesterday!!
Thoughts and experiences?? Appreciate it.
