I would SWAG it as 30 ish MAP flat wack and 25 ish at 100

Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
About 18 mate.
Mine is peak. When I'm giving it the berries....
I have 2.5" lift (closer too 3"), 33's, roofrack, drawes, winch ect..
I Have a Voltage Modifier on my MAF in my troll so I run 9 psi roughly at 100km/h, EGT'S around 320 degrees.
Max boost at 20psi and I can hit that going up a hill or headwind putting my foot down and sit on 20psi all day long till I reach the top.
EGT'S even towing nearly 2ton with a/c on I'm struggling too go over 500 degrees.
I'm averaging 11.8ltrs per 100 atm on Highway without towing, around 15.5-16 towing just under 2ton.
I'm still using factory MAF housing as well and VNT turned down 1/4 of a turn
I may get a boost spike too 22 psi but drops straight down too 20psi and sits there till I back off

I have Dawes and needle valve on mine (EGR block). Driving to work today if I gave it a bit it would go to 29 psi MAP but stayed around 20 most of the time so sounds about right until I get onto the highway.
Too low... give it a bit of a tweak I reckon.
I recall someone saying crank it till it limps and back it off a tad... or was that wheel nut torque (do one up till it snaps and back the wrench off 5 ft/lbs).
Mind you I've never set up a Dawes and Needle so what would I know

Just remember. The max boost is relative to the cruise boost. I.e 100kph boost. The best results I have found is around 8psi difference between max boost and 100kph boost. So the higher mac boost you go the higher cruise boost too. If not you will find the spool up rate of the turbo too slow and the engine sluggish. I will vary a little between cars but thats an average.

I'll try that on the weekend Mudski. Car feels pretty good though. When I had it set on boost it would sit around 12psi at 100 and max at around 18. Its a CRD so running a bit more boost is probably good for it. I read on here that 10psi at 100 is good but I could not adjust it down that low as the spool rate was too slow and car felt sluggish. When I adjusted mine I found a sweet spot and if I tried to go over (more boost) or under it the car did not run as well. Might tinker with it a bit more when I get the chance.
With the scangauge set to MAP what is a good max boost? 35psi? I think that equates to about 20psi boost. When I turned the car off today I kept an eye on the scangauge and it came down to 14.3 psi which I think is the atmospheric pressure. That would make the 29psi MAP about 15psi boost which is pretty good.

That's pretty well what my crd is set on and feels good. More boost did have my egts lower when I was flogging it but went to limp mode after about a week so I took 2 psi out of it. Spikes to 20 then settles to 18 and cruise is about 12 ish but very hard to measure. Haven't hit limp again.
Been driving my auto in the lower ratio the last two days EGTs are around 200C
so revs has a lot to do with it as well
04 ST 3lt auto, not enough Mods to keep me happy, but getting there
well just drove to the doctors about 15 k using the lower ratio on the auto
cruising on 60,70 and 80 egts were 200c they went up under throttle and settled back very fast
Its about 30 degrees ATM in Melb
