Guess the numbers
I have a 2008 5.3 with 35k miles and I have jba shorties and intake and exhaust. I'm taking it to get a tune. What do you thing the rwh will be at? I'm hoping around 320? Is that reasonable?

260-290 RWHP and similar torque depending on the dyno type. If it is on a Dynojet it will be toward the top of the range. If it is a Mustang dyno it will be on the lower end.

A stock 5.3 with a good tune and long tubes would make about 340 HP to the flywheel. Deduct 18-22% off that for power loss through the drivetrain. That makes for 265-278 HP. I gave a little wider range because you could end up realistically between 330 and 360 HP at the crank.
