AE or spare IDM in Seattle? I'll buy dinner and beer.

Does someone near Seattle have AE or a spare IDM I can try out?
I'm about to give up.

Misfires, won't rev above 2k ish, doesn't build much boost, blows white smoke when you get on it hard. There is no performance chip on this truck.

I've replaced:
All 8 injectors with Rosewood Stage-1
CPS with a new Ford dark gray

I've unplugged the following one at a time, with little to no difference:
EBPV (still unplugged)
EBP Sensor
MAP Sensor

I've checked the fuel pressure, 50-60 at idle and WOT

I bought Torque Pro for my Android, and this is what I'm seeing while driving. The low value is at idle, the high value is a never-exceeds value at WOT

IPR Duty Cycle 14-35%
HPOP Pressure (Confirmed with gauge) 650-2300psi
Injector Pulsewidth 1.1-1.7 ns
EBP 14.5-21
MAP 14.5-20
Boost (Confirmed with gauge) 0-5 psi

Torque Pro says there's no codes.

All of the common-to-injector pin (2 to 3 and 3 to 4) resistance measurements are dead-on 3.5 ohm.

Logic says that it's not building boost because it's not building EBP because it's not getting enough fuel. However, I am definitely getting white smoke and a misfire when I romp on it, which leads me to believe that the injectors are firing at the wrong time. I replaced the CPS with a new Ford unit and there was no difference.

All I have left is to do a compression test, IDM, and maybe the barometric pressure sensor.

I really want to slap another IDM on there and see what happens. AE would be awesome too, so that I can check Barometric Pressure, TPS (Although not likely the issue), buzz test, CCT, etc.

So if you're within a couple hours of Seattle and you have AE or an IDM, please let me know. I'll buy you dinner.

This *might* work in Torque for you to read barometric pressure:

Long Name: Barometric Pressure Sensor
Short Name: Baro
Min Value: 0.0
Max Value: 30.0
PID: 221442
Scale Factor: x1
Unit Type: PSI
Equation: (((A*256) + B) / 4.01463133) * 0.145038
OBD Header: C410F1

Add it as a custom PID, then scroll down and hit the test button. If you see a response that starts with something other than 7F, it should be working. It works for me on my early '99, and I found it while trawling through an OBS thread on another forum.

For a buzz and CCT test, you might look into Car Gauge Pro. I don't know how compatibility with OBS is, but if you research it and find it to be compatible, it's only 6 bucks on Google Play Store. It is NOT user friendly at all, but I use it solely for buzz/CCT/KEOE/KOER, etc. tests.

I read on a forum that hearsay isn't allowed on the Internet . . .
