High EGTs, Boost Maxes Out

[gimmie11s]

You should be hitting 27 psi at or around 2100 rpm with that turbo.. +/- 100 rpm

 

Do you have a boost controller or does that Smeding turbo have a higher pressure wastegate or adjustable boost elbow?  Maybe attach a picture

It should be set for 35 psi from their site. I was having an issue with the wastegate hose popping off. I thought of blocking it off to disable the wastegate to see what that does.

You have v2, it's been plugged on my truck for few years now.

I got some DFI 7x.010 injectors from a friend for $350, maybe 50 miles on them and gonna work on my gauges this week also. 

[gimmie11s]

That'll be great.  Let us know how you like them.  I have 75hp injectors like you and feel like i need more.

 

Im still able to get 40+ psi with my injectors though, which brings me back to something being funky with your set up as it sits.

May want to check pop pressure before you put them in, I personally would not put them in unless they are around 320 bar, in guessing they are around 300 now. Be ok but smokey.

You think the injector will wear out that quick with 50 miles on them?

I think something else is up.  you need more injector for sure, but something is off.

No, but most injectors that size are popped lower for more flow. Just saying if it was me I'd want them to be in that 320-325 range. 

Have you checked for boost leaks

[mechrisme]

Installed the injectors, gets 30 psi on the fuel saving mode and will hit 35 and then the wastegate opens so they seemed to of helped out.

I towed about 11k lbs I wanna say up a steep hill without a good running start, EGTs were about 1400 and boost was about 30 psi, decent I wanna say

[gimmie11s]

On what level did you see 1400 degrees?

 

we just towed our 14k Lb 5er up a 10 mile grade that ranged from 4-6%... on level 3 with 75hp injectors and about 25psi out of my hx40 hybrid... the max I saw EGT was 1100-1150.

 

i feel like I could have gotten into some wiretap for more power up the hill but she maintained 50 mph at the steepest part of the hill so I suppose that’s enough.

I typically run level 3 unless more power is needed. Anything with wire tap I could push through the 1,200 barrier pretty easy. Even towing a trailer on level 3 does extremely well.
