Looks a bit better than bone stock AFR curves, but not much.
You'll gain some power and much smoother feeling after getting it tuned, as well as responsiveness in throttle transition states.
Once tuned your likely to pick up a couple pounds of torque, a broader torque plateau before it starts to fall off a few hundred RPM, and about 10 whp if tuned right, with little/no roll off up top, just a HP plateau until redline.
Another fine example of my entire PSA from a long time ago...
$250 says if he did a pull in 3rd, it wouldn't swing lean above 5500, it'd stay in the 12:1 range all the way to redline.
