7.3 Idle Surge
So I have been scratching my head on this one for a while.
Truck idles fine when in park without ac or turning the steering wheel. As soon as you turn the AC, turn the wheel or shift into drive it begins to bog and then rpm spikes before leveling off.
When you remove the load and put it back into park, turn off ac or stop turning the wheel the rpms spike and then drop before finally leveling off.
So far the truck has new OEM:
ICP,IPR,UCVH,CPS,EBP/tube and new engine wiring harness.
I’ve also put on Full Force Diesel 205/30’s and running 1023 tunes on a hydra.
I’ll attach a YouTube link so you can see what I am taking about.
what are yalls thoughts?

I have not yet, but I definitely will now!
After hearing all the bad stuff about ffd injectors, I wish I would have known about you guys at the time of my purchase

so I tried the 00 bypass and it didn’t make a difference.
I even tried some of the stock hydra tunes and it seemed a little better but still does it.
i was seeing my ipw around 3 ms at idle though. Does that seem a bit high?
it was around 4 ms with the stock hydra tunes

not that I noticed, but I wasn’t paying attention nearly as much before I replaced them.
I remember the truck feeling more lively on stocks with generic TS 6 tunes than it does now though. I almost regret fixing something that wasn’t broke haha
