Does anyone have pictures, of the intake area of their 7.3 ported heads, they would be willing to share? I am looking for increased performance for a daily driver/play truck and not full-on racing/pulling. Considering attempting the task myself. Thanks.

Thanks for your help!

New leads arrived and no issue found with crank position wiring. A used PCM, with same strategy, was acquired and installed. As soon as the truck reached the required hpop pressure, it fired off and ran as long as the throttle was slightly applied. Thanks for all your help and input to narrow...

Have some longer leads ordered for my meter so waiting on them to perform the individual conductor resistance checks. Thanks for all your input and help.

The frequency between pins 30 & 40 ranged between 163-175 hz. Resistance between pins 30 & 40 measured 358.1 ohms (through crank sensor). Still haven't checked individual conductor resistance.

Should have searched prior to posting but found several videos of the 6.0 injector buzz test using different software/test instruments and my injectors sound identical to those on the videos. The "buzz" I am hearing is apparently normal. The AE software actually runs the test three consecutive...

All the injectors have a defined click but three have a buzz sound. The buzz sound is what I am accustomed to hearing on my 7.3 injectors during a buzz test. The AE software indicates the test passes. It could be I am comparing two engine injector sounds that are nothing alike.

The P2552 error cleared today without touching the FICM. The plugs are locked in place. I ran the KOEO test and it passed again and the Injector buzz test said it completed successfully but only three of the eight injectors actually buzzed this time; the other five injectors just clicked. The...

I have not checked the Crank sensor wiring to the PCM plug yet. The voltage is staying above 10v while cranking and I am leaving a battery charger/booster connected to make sure the starter gets steady voltage. I don't have access to an oscilloscope. Attempted to get the injector pulse width...

The block was clean under and around the cam sensor. The original sensor sensor was replaced with a new OEM sensor. Haven't recorded the injector pulse width yet but will try to get it later today. Thank you.

Checking between pins 43 & 31, frequency measured 1.22 but the voltage was a steady .09vac. Is this an indication the new cam sensor is bad?

The wiring has checked good when checking continuity from one end to the other with less than 5 ohms on each conductor. The wires measured 872 ohms when measuring through the sensor. Will try to measure the frequency and AC voltage tomorrow if weather permits. Thanks for your suggestions and...

The cam sensor checked out at 872 ohms which is within spec. The engine didn't start after having the block heater on for more than 12 hours. The RPMs went as high as 260 but settled at 177 and were steady for several seconds. This is slower than normal but not sure if it is below the minimum...

The IPR voltage was 11.5v this morning which may be low due to my leaving the key on overnight. The truck isn't giving any codes other than EGR related; the EGR has been deleted so they are expected.

The FICM is modified and puts out a constant 52v. The ICP has 5.06v and the cam sensor has 3.08v. Haven't checked the IPR voltage yet. The truck is currently plugged in and warming the block. Will try to start it again tomorrow. The fuel pressure builds to 50+psi when the key is cycled but then...
