For off-road Mitsubishi and Hyunday 2.5l with 4D56 and 4D56T engines: immediate turbo reaction, torque advance, power increase, fuel consumption reduction.

Anyone know anything about this VGT turbo made specificly for the 8 valve 4D56? Boost controlled so you don’t need an ecu or two valve controller to run it. Pretty much plug and play.
I've also run across this recently and just came here to see if anyone else has any success.
Andres Muriel at Saito claims it's not an original Mitsubishi vnt, but rather a Garrett base VNT with a Saito "tuned" compressor wheel.
He also confirms it will bolt on to a 4D56/ 4D56T, as in the models mentioned in the add.
He believes it should also bolt up to the 4d56 in an L300, though he cautioned that it's not the same size as the stock T04.
When I asked him for any compressor flow maps, or any data he has on it, he said the following:
"We don't have any data, but with a correct fuel pump calibration you can easily gain 30/40% of power more compared to the original."
I've just asked him how exactly they "tuned" their compressor wheel, if they never did any testing or recorded any data.
Maybe they just eyeballed it and found it made a bit more boost?
Personally, I like that it's a Garrett but I really dislike that they are claiming to have "tuned" it but have zero data on their product.
You'd think that that would be a requirement for tuning a compressor wheel...
I imagine the process as:
1. Make a flow map of the one they're basing theirs on.
2. Modify (tune) their compressor to adjust that map
3. See how the flow maps compare
4. Repeat steps 2 and 3 until desired results achieved.
