Dyno tie down advice

[lswing]

I'm hoping on a dyno soon, and they wanted some details before I bring the car up. Best spots to hookup and tie down? One of my tow loops on the under/bottom rear is already torn. There the one behind the flap in the front bumper, but what about other spots that people have used?

Going to be able to check wideband o2, fuel, and boost live, along with other parameters on the laptop.

Thanks!
