This is (...I Hope...) MORE Good News in that I TOTALLY FORGOT to mention another possible component that can go sideways on the Y2K 5.3L Engine and that is:
The Fuel Pressure Regulator. Check out this First Video for What it is... Where it is... and How to Repair it by performing a Very Simple R&R:
And...
WOW… That choice of
BTR Stage 4 Cam is a Pretty BIG Bump Stick that will not only require a “Custom HP Tuners Tune” ...but also require a much Higher Stall Torque Converter just to make the Truck even vaguely Driveable on Surface Streets. Unless you have already purchased such an aggressive Camshaft Kit… You might want to reconsider after dropping in on my current (and much more modest) TSP Stage 2 212/218 112 LSA .550”/.550” Cam Kit, S/S Headers and S/S CAT-back Exhaust Project.

The second link involves my becoming heavily invested in all of the requisite HP-Tuners SW & HW and an Expensive HPT Training Package from “The Tuning School” down here in Florida to be able to eventually perform my own tunes as well.

Whenever I'm working on Complex Mechanical Projects… I tend to be as comprehensive as possible in covering all the details… so these can’t be considered “Light Reading”. Of course, I could be completely missing the possibility that you yourself are already an Accomplished “Tuner” and if that turns out to be the case… Please contribute your comments and images of your work when things get going either on my Threads… or by all means… Start some New Ones!
If not...and you are just now getting into the "Tuning" side of The Build... I would urge that your "Knock Sensor Delete"
be only a very temporary thing...lest you accidentally run Way Too Lean ...say 17:1 at Much Higher RPM and do some serious damage to your engine. For the first few tests ... KS Deletion should only be done for the initial problems related to Starting and Idle problems...then perhaps after the initial tune is added... a little local driving at very low speeds to figure things out. You DEFINITELY need an AEM Wide Band Oxygen Sensor and Gauge Kit installed.... to WARN you before you get
Way Too Lean!
