Here my impresions ..
The most important thing that I found are the EGT range .. good ( or not to say perfect ) working injectors and IP .. and at factory boost setings 10 PSI the EGT fly direct to the heaven in 1 min .. pedal to metal .. even with the 3" straight pipe exhaust ..
You can reach easily the 1250 barrier in less than 10 km of full throtle .. if you tune the boost a little up, they can be controled better ..
I'm running 14 PSI right now .. not necesary to say, that I'm really happy at the " safe " range of boots. But also take a run @ 20 PSI ..

woooooohoooo !
What a powa !!!!!
Other note are my oil press .. I remember clear that the FSM for my 2H claims for at least 4 PSI at idle @ normal operative temp and 36 to 64 PSI @ 2000 rpm at operative temp ...
And actually the 1HD-T can meet those numbers with more than 20 - 26 PSI @ idle ( depens on the hard or not hard run ) and 48 - 54 PSI @ 2000 rpm ..
The only thing that make re think about it, it's the oil press at cold start .. that not pass over 62 PSI when in my 2H are more than 85 PSI ..
thoughts .?
