How did you not see it losing fuel pressure, if it was?

What injectors are in this? Did you ever say?

Supercharged, cam with overlap, big injectors, probably not the best candidate for first tune project. Stock vehicle with CAI and headers, little different story.

And that ^^^^

When dyno tuning I prefer to have the sensor up stream in a bung versus in the tailpipe. Only use the tailpipe sniffer when I absolutely have to. Upstream in a bung they react faster. Not necessarily...

This vehicle should have a permanently installed fuel pressure gauge and wideband where you can see them while driving.

I'm diggin that 63 Galaxie. Pop rivet some old license plates over the holes in the floor and we be cruisin LOL

Both logs the commanded EQ and commanded AFR stayed the same. Fuel pressures stayed nearly identical also. Biggest difference in the logs is your long term fuel trims. On one run they were negative....

There are no mind readers here. Only me with my crystal ball. It does take some amount of explanation of what/when/how kinda stuff.

It's still a train wreck. Why would your VE table go to 175 Kpa if the engine is normally aspirated? You can edit the X axis and you'd have great resolution.

Why would you have +8/-8 degrees...

Thanks for confirming. I was pretty sure this was the case.

The DW 360 should be enough by itself. You shouldn't even need a secondary pump at your HP level.

Why don't you email support?

Damn and he's gonna argue with you about how that's not abbie normal.

They kicked me off there over 10 years ago after I told Jannety he was an idiot. Or however you spell his name.

Only if you wanna put a motor in it.

If the vehicle is all stock put your laptop and HPtuners away and fix it. Buy a subscription for your vehicle from alldatadiy.com. Look up all your codes. Print the trouble trees and accompanying...

Post the tune file and state the specs, mods, etc.

I don't know that the 3 is backwards compatible with the older software versions.

What interface are you using?

Did you email support and tell them the DTC switches were blacked out again? That's where I'd start.

That was going to be my next question. Larger fuel pump lobe? Shimmed pump? Anything different about it mechanically or 100% OEM setup?

OK well start ohmin shit and writin it down. I'll check some tomorrow and report back.

Do you have anything "known good" to compare it to? Like maybe a known set of LS3 injectors?

Now that I think about it I'm pretty sure I have a full set of LS3 and LSA injectors in the shop. I'll...

I agree completely, one of the biggest factors is going to be the DVOM and the voltage applied for the resistance check. This is why I very rarely use resistance checks for anything but an open...

Are you looking for a specific resistance to determine if they are indeed a specific injector? That's a new one on me.

I would think the same body injector across many flow rates is going to have...

First thing I'd do is throw it in the trash and put a stock plastic intake on it.

But, other than that, you should pull the map sensor out and make sure the hole is drilled through.

Short...

Did the pressure drop off because the low side couldn't keep up? Did not look at the log, just asking.

The pump did not physically break, you just got a low pressure code?
