Thanks for letting me know! I'll look into them.

ive heard alot of bad about glow shift. My cousin has them in his 6.0 and hes constantly complainging about them going out or the lights going out. I have a autometer right now but whoever installed it put it post turbo and I'm pretty sure the fitting is so rusted I'm not getting it out. So I was going to go with either a cts3 monitor with their eas and a hydra programmer or gauges and a hydra.

Rosewoods are a good option. I went with rosewood 160/0's and love them. They did not make too much of a difference in fuel economy and they smoke quite a bit. I have a hydra tuner with jeli tunes and it has some good power to it. I would like to eventually upgrade the H-POP but it has not had an issue keeping up with the injectors. I also have not had any issues with egt's, although I do not have a egt gauge (definitely recommended) I know the truck has not had an issue. I always reccomend JeliBuilt tuning after my experience with him, he was very helpful diagnosing issues over the phone in the past and his tunes came out great.

It has ran for thousands of miles being beat on, daily driven, and abused and still runs perfectly fine. That would be my guess, all that is done is injectors so I don't see how that would put me over the edge on egt temps. I've seen plenty of other trucks with more aggressive setups with no issues so I'm banking that.

pardon my potential ignorance, but wouldn’t this be exactly the way to create egt issues?
adding a significant increase in fuel sent to the cylinders, without adding any meaningful additional air?
I smoked for about a decade, I didn’t have access to medical imaging equipment. That doesn’t mean smoking wasn’t bad for my lungs, it just means I couldn’t see the results.
An egt gauge is fairly cheap easy to install way to keep yourself from melting a piston. If a guy can afford a set of injectors, he can probably afford some gauges.

I just have not got around to buying/installing an egt gauge. Your comparison does make sense to me, but this is something you would notice a lot sooner than smoking. You can quickly burn up a piston or cause damage to the engine in ways you would most definitely notice. The injectors have been in for at least 9k miles and climbing.
Check out this thread, this is a very similar truck with perfectly fine egt temps. https://www.powerstrokenation.com/th...h-egts.145792/

I can easily break 1000 degrees with stock injectors and a hydra while empty. The truck will run at 1000 degrees all day and be fine,1250 seems to be ballpark number most people begin to get concerned about.
I can’t picture that getting better with 160’s on a stock turbo and a stock hpop that might be struggling to keep up at this age.
I am by no means an expert, it sounds risky to me but I think lots of things and know very few things.
I’ll stop derailing the thread now, sorry.

7.3s will run even with damaged engine parts. Do some reading on how many have been torn apart only to find a cracked, damaged, or melted piston, and the truck was seemingly running fine before tear down.
there are multiple factors that affect EGTs. Fuel only being one of them. Throw in some hpop data, a variety of tuning, and turbos and you have an array of places where EGTs can get out of control. I have a set of 160s on the shelf that I haven’t installed because I don’t have an EGT gauge. I don’t want to risk damaging my truck. I need it work, not being worked on. I hope you don’t have EGT problems, as I don’t want anyone to have to rebuild a melted down motor, but I don’t think it is sage advice to think that you can drop those in and be carefree about EGTs.

I completely understand where everyone is coming from being concerned. I'm not saying that an egt gauge is not needed and that I'm not worried at all. What I am saying is that from what I have experienced, I have no problems yet. Like I've previously stated, I am going to install an egt gauge very soon. I am sure the truck will have decent readings and I will make sure to update with my temps when it is installed. Driving style makes a big difference, he said the max he ever saw was around 1100 which is a safe number. I could see higher or lower, not every truck is going to see the same reading. Powerstroke Central has a video installing an intercooler and egt gauge, and seeing how much of a difference it makes. At the time, I believe the truck had injectors and a turbo. Temps dropped 100 degrees and I believe he was seeing some 1300 degrees which is certainly a lot. Either ways, I'll make a post after the gauge install and give everyone an update and see what they are.

No way a stock HPOP is keeping up with good miles on it. Mine was falling over with stock 90cc sticks and a hot tune. Parts wear, especially ones lubricated by oil.
I would probably drive on stock tune or really mild fueling added with the 160s until you can monitor more data.

I have replaced and upgraded many parts on my truck over the last few years in preparation for new injectors. Once I added EGT gauge, it was like I really started to understand what my truck was doing. I now religiously drive by the EGT temps monitored. I now know where my truck performs the best being boost pressure, trans temp, EGT and how they all work together.
Pulling a hill and being at the wrong rpm has shown a drastic contrast in EGT. I assumed prior to the gauge that a lower rpm and speed was better but I was completely wrong. I found my trucks sweet spot on a hill that I pull few times a year and it was in Drive, 27-2800 rpm, 60ish mph and boosting ~20psi. The EGT maintained a 950-1k. With that data provided by the gauges I now understand why my truck seemed to struggle with this particular hill in the past.
I now agree that gauges should be the first thing installed. Plus the fun part about the gauges are receiving data of the benefit or disadvantage of each new part you add going forward.
