I wasn't watching my ebp but on this last trip I kept throwing 2 SES pulling my 10K lb 5th wheel toyhauler on steep passes. High ebp and Low ICP pressure. I'm running stock injectors and stock turbo with the KC Turbine upgrade. Running the 1023 Heavy Tow tune to keep EGTs below 1300 and running about 26 psi of boost with my foot to the floor and going about 55-65 mph depending on the steepness of the grade in 3rd gear with my auto trans.
I ran 1023 tunes for a couple of years with the MST and they did well. Although, when I swapped in a Borg Warner SX-E and T4 kit, the 1023 tunes were terrible. By only changing the forced induction portion of the system, it made the tunes worthless to me. Before going out in search of new tunes from the various shops, I figured I would try the PHP tunes that came with my Hydra. I love the 65 HP Performance tune with my application of towing heavy cross country, but I have a ZF6 truck. So, there is only one piece of the puzzle that I need to be happy with since I control the shift points with my right hand.

I've never seen a high ebp code before? Just seen overboost code and the low icp code which is very common with stock injectors and some tunes. Some tuners ask for more icp then the stock hpop can provide for stock split shot injectors.

Try some of the "canned tunes" from PHP that came with the Hydra you own, if that is in fact what your tuner chip is. If it is a 6 position, disregard my comment.

......Injector wise I was disappointed to hear Rosewood closed their service center, because I was planning to just drop the whole truck off for a few days and let them pick it apart and fix/re-install the original injectors, but now I’ll probably just have to order a set and have the Ford truck shop over in Mishawaka do the swap and send the old ones in as cores. Maybe if they can rush a turnaround on mine I could do that. I would be curious to hear the full report on what I’ve had going on with this current set but that would cause a lot of downtime is the problem. Maybe they could just indulge me and let me know even if I wasn’t getting them back.
Yes, we closed our Service dept, but our mechanic took all that over and is doing his own thing, here in the same building. We work with him all the time when he has a 7.3 injector job to do.
So keep that in mind. However, he just had major surgery so he's out till October.
Anyway, we can always schedule your injector rebuild so that your injectors are only here for a day or so, that's never a problem with enough notice.
If you are in northern IN figure 1 day shipping each way, so it should only be 3 to 4 days from the time you ship to when you get them back.

Good discussion guys, thanks. I am interested in seeing if anyone out there wants to trade a lightly used (4 years and 15k ish mile) 364.5 for a similar 363 sxe... i am going to put the interest out on the marketplace and see what happens. I am quite happy overall with the current setup but I do agree that bringing the turbo light off point down 3-500 rpm would help the power band out tremendously.

I’m pretty sure the case is a different size, but is it possible to just swap out the turbine and compressor wheel to save a few bucks?

My 364.5 started it's life with the 73mm....I swapped the housing and shaft for a 68mm....much better.

Hmm that’s a good question, I’ll have to dig in my files. I’m assuming its the 73.

I also want to make you aware that actual AC code injectors are extremely rare. Some guys think you can go to International and just buy one if you need to, but you can't. This may be a factor to those on the road. If you run a bad batch of fuel that damages an injector then you are stuck until you get a custom injector sent to you, you can't just go buy one. Our last set of AC's took almost 10 months to get. We've had another set on order for about 4 months now.
Anyway, we (as well as others) can build you a set of 160cc Stage-1's which is what the AC codes really are.
So keep all of this in mind with planning your upgrades.

I suspect that came about because it was true in the past (probably prior to 2020).

I did find this from a thread in 2014. It says new. I assume that means that it is not a re-build.

Alliant also shows New AC injectors in stock.

My AP rep can't get them anywhere, and Alliant Power doesn't have any in stock, anywhere.
Even RiffRaff doesn't have a set to ship (try to add 8 to your cart and pay - you can't.)

That is good to know! I was under the impression that one of the advantages to AC injectors was that they were an off the shelf item because they were used in certain factory applications.
I suspect that came about because it was true in the past (probably prior to 2020).

I don't see a way to add the AP ones to my cart but I'll take your word for it. I'm not in the market for injectors; just keeping my ears open in case my factory ones eventually crap out.
