What sort of max water temps have you scored on the beast Daz mate?

Just the Factory guage but can honestly say i have only seen it move once in 2 years and that was from normal running at 1/3 to about 1/2.... soooo Bloody good mate. I really was concerned.

Mine generally behaves itself perfectly don't have an aftermarket gauge just the trusty old GQ one. Did get warm on some of the big east gippsland hills heading up in on weekend to Coota, only had a 6x4 trailer but was over 30 degrees and holding it on 100kph, got to around 2/3 on the guage which is fine but is always nice to see it under half lol. They are some pretty big hills those one which go far a fair way tho. EGTs are always low can get it too 500 but that's pushing the buggery out of it it ap a mega hill in 5th or 4th. Getting the ufi pump fitted now hopefully my issues are sorted and everything else is as good as it was if not better. .

I'm actually worried mine runs to cool. Prior to the tune it just shaded 80 on the gauge with EGT's at 500 on a couple of long 4th gear pulls. This with the backpack camper, 190lts water and full fuel 145lts.
Now I can't get the thing past 75 no matter the load and EGT's max out at 450. My concern is it's not getting up to full operating temp and so not getting max efficient fuel burn.
Tea kettle?? Pah! Lucky to get a tepid shower out of it!!

Interested with new tune: higher boost? higher AFR?

did not mean to report your post - sorry (digit slip)

Nah! Got about 2000k on it before tune. Went in with 146 hp came out with 166 so mechanic did a fair job on a "by ear" tune to start with.
The tune got the Ebc up n running cos was a mob of nuffies , me top of list, when it came to that thing. No idea about AFR, all 'ol mate said was he leaned out the bottom end a bit.
All Greek to me anyhow. As far as mechanical shite goes I know enough to turn the ignition key.

OK, to "lean out" the AFR (Air fuel Ratio) has been increased. With bottom end he means at the lower down rev range, has reduced amount of fuel in the air fuel mix.

Should mention, turbo is Garret 2863 gated at 14 psi. The guys at Gympie diesel and dyno still managed to tweak 16 out of it so EBC overboost shutdown is set there.

Have tried searching before for the official TD42T optimal water running temperature Touses mate to no avail. I would assume it’s somewhere between 80-90C like most others. I know my utes 6.5NA is military listed at 88C and ran a whole lot more stable once I exchanged the Aussie 76C TS’s for correct Yanky 88C TS’s for its spec.

Was beginning to think along those lines, hotter thermostat. 82-85 if I can source one.
