I personally wouldn't bother. All the chips do is make the computer think that that oil pressure supplying the injectors (ICP) is lower than it really is. So the computer compensates and tells the oil pump valve (IPR) to divert more oil to the injectors, thus increasing injection pressure. Your initial throttle response will be more aggressive and with that being the case you will probably see your fuel mileage actually take a hit.

Thank you for the info. I kinda figured if they actually worked people would be raving about them...........but it never hurts to ask.

I actually got one of those "performance chips". It plugs into the ICP sensor. Didn't do a Damn thing. Zero. Nada. Maybe I got a bum unit, I don't know. I put a call to the company and I'm waiting to hear back...not exactly holding my breath...

I really hope to hear more about being able to swap out an ECM. Even if I could go up to 210 would be nice... now just need to figure out where to find a working one... maybe a junkyard? I see s bunch on EBAY, but the seem like they are not programmed...

Yeah, I've no interest in those either. They're a ripoff.

I like to use sites like this to look at all of the different injectors that came in the 466E over the years. The descriptions are not always 100% accurate so keep that in mind. My engine is a '98 230HP High Torque with 660 lb-ft of torque. It originally came with "BG" injectors but those were discontinued so the recommended replacement was "BJ" injectors. These injectors are good for a 250HP tune but I would assume my ECM would need to be reprogrammed to take full advantage of that extra 20HP.

This is more or less what I've found too.

I've said this before but I'll say it again. The best bang for your buck to boost the power in these electronic engines is going to be a water/methanol injection system. Upgrading injectors, turbos, hpops will get very expensive very quickly.

From everything that I have seen when a water/methanol system is applied to a turbo diesel engine you can reliably count on about a 10% increase in horsepower and torque. That would push my bus up around 250HP/725 lb-ft of torque. Still safely within the limits of my MD3060 transmission. As soon as I scrape together the cash I will be installing a system from Snow, Banks, or AEM.

But I do believe that if you can find a working ECM from another 466E within the same time frame you shouldn't have any problems boosting power that way as long as you have all the necessary hard parts.

Let the navistar dealers be your friend.. if anyone has a very similar year bus with different HP rating.. simply call a navistar dealer and say you need a turbo and a set of injectors for your VIN.. and then for the VIN of the other HP rated bus..



then compare part numbers.. cross reference and see what if any differences exist.. the 175 - 215's all seem to be the same when you look at buying reman Long blocks.. so that tells you that pistons, cams, HPOP, etc are the same up to 215..



the 444E's are the same 99.5 Model year plus from 175 - 210 Horsepower. all AD injectors except for one AE added in the 01 model year for a "knock" issue..



with the 444E's it was pretty easy to tell as the valve cover stamping with the HP rating is the same sticker part number (yes the sticker has a part number) up through 210 and then changed for 230 and 250 (didnt even know a 250 existed )..



im not sure if you guys have stickers on 466E's with different stamps ?



in the 444E's the HPOPs are all the same.. in fact from what I read, the HPOPs on the 444E's are more powerful than the ones ford used .. as the tuner guys are putting 444E HPOPs on their fords.. the HPOP for the 466E may be the same.. all it is just an oil pump.. not a particularly high volume oil pump just a high pressure oil pump. when you get into making high revs thats when your HPOP requires more volume.. the ford guys put 2 HPOPs on as they tune heavily and run revs up to 4K+ in some cases.. each stroke of the injector piston requires an Oil shot..



some people claim you can gain Horsepower.. quite a bit of it by upgrading your injectors and "fooling" your ICP.. im about to embark on upgraded injectors.. I got a set of 15-20% higher flow injectors for my 444E.. the horsepower gained claims to be similar (if not more because of turbo) than that.. if I gain 15% from my 190.. i'll be at just above the 210 my engine internals are designed for.. I dont want to over-run my internals just wake it up a bit..



my guess is upgraded ECM's sell for quite a bit over the low HP ones.. and whatever you do never plug NAVKAL into an ECM that wasnt built for your Bus.. NAVKAL will mismatch the VIN on the ECMand the data you enter into your account and downgrade it.. ServiceMaxx is perfectly safe.. it doesnt reprogram the firmware..

I'd be curious to know whether the 444E and 466E share HPOP designs. I've never seen them listed as 444E/466E HPOPs (like they are interchangeable) and the Powerstroke HPOP is not the same as a 466E so my assumption would be that they are not the same but I don't have any verification.

The 466E has two different HPOPs, one is the "021X" and has a 5.3cc pump for lower HP applications. The other is the "020X" and has a 6.5cc pump for high HP applications.

I second cadillackid,
In the case of my 2006 2500HD and a 2006 3500HD single wheel the only difference is slightly bigger tires 245 to 265, steel Rims and an extra leaf in the spring pack. Everything else shared the same part numbers.
I found on several sources the DT466e is good for Power output 170-350hp (commercial), 375hp military
https://en.wikipedia.org/wiki/Navistar_DT_engine
I don’t see why a simple tune couldn’t bump you 50 HP.
I would look into some of the more reputable Diesel tuners and see what they have to say.
Using something like a https://www.efilive.com/ might be just the ticket you are looking for.
