For comparison, his curve is 180tq peak, falling to 130tq at 7k. Rover's BP05 EFR setup makes 205tq and falls to 155tq at 7k. He makes the same torque at 3000rpm and 7000rpm, Rover makes the same torque at 2800rpm and 7400rpm. That's exactly what I would expect given the differences (BP05 EFR vs B6 GT2560R).
If it were an airflow issue, the torque curve would be screwy, or it would make big torque and no power on top.
Sticking with my original guesses - either the motor is dead or the dyno is a mega-heartbreaker.

Dynapacs can also read super low or super high or whatever. They're kind of annoying like that and can even change from generous to heartbreaker during a session as the hydraulic oil heats up. But looks like its a T25 problem. I'm with brain, drive the car and enjoy it, and if you feel like you need to do rods and ****, do it to a 1.8 on an engine stand and not the 1.6 in the car.

Not that good, but close enough to consider getting the turbo.
You are right. I was looking at the garrets, and saying, how are these still so much money? I think the efr is a great turbo to grow into. When I finally get around to building the engine, I'll have enjoyed 220whp at wastegate pressure for a good while on the stock block, and I'll just run more and more boost as I get used to it. seems like people are making into the mid 400's with the turbo, I feel like that will be enough.

The advantage to the 2560 over an EFR is that (I think) it'll bolt to all the hardware you already have. So no, it's not the baller setup, but it's a decent upgrade from a journal bearing T25 for a lot less money than an EFR.
