Thought I should post this for anyone looking for an european hybrid turbo option.

I tried another cheaper german vendor first, but those turbos didnt last long. TTE seems to be great quality so far, but I can't speak for longetivity since I'm only at about 10.000km.

So far I've managed to push these to 650whp with a not too aggresive tune.
This is on 100% E85.
The torque was kept low in the lower range because AT and OEM rods/pistons.

On this run wgdc was about 65.
I have some issues in the higher rev range where I also get misfires sometimes, probably because of bad injector holes. I plan to try and wrap them in teflon tape, or install the spare head I have laying. I think there are a few extra hp to gain in that area with the same tune.
