Gt2871 dyno
Build details in sig. Whatcha think? Keep in mind that this is a dyno dynamics dyno. They said that it generally reads 17% lower than a dynojet.

Looks good but needs absurd flow and an intake mani.

K, now I get to make fun of you. Get that POS muffler off the car and replace it with a big Magnaflow. Something you can literally roll a tennis ball through, please. There's no excuse for torque that doesn't peak until 5200rpm like that - you should be able to move that entire chart down 700rpm with just a muffler change.
Also, find a dyno operator that knows what he's doing. Starting pulls at 3500rpm =
Fix those two items and you should be able to see full torque in the ~4000rpm area, especially if that's a .64 A/R 2871R. Regardless of what the actual torque numbers are, just the torque line vs. RPM is pretty poor, and I bet it's all due to muffler and dyno operator error.
