Came up blurry for me, can't really read it. What were the baseline numbers?

They have laminated the print out, is this any better?

Much better... Surprised it made close to its peak torque so low, not bad for a stocker. You'll see 150hp at the wheels I'm sure with the blower and cam if not more depending on supporting mods. Maybe close to 200hp since you're doing headers and exhaust. Which heads are you running?

450/475 after blower, go fast goodies and tune..what ye all say?!

Edit-due to mustang dyno..

Kooks headers, the guy at the shop mentioned that cats may get clogged up.

I rigged up an exhaust pressure tester and my cats haven't gotten cooked yet. Have dynatech longtubes and catted y pipe. I'd imagine a hot tune could do that, but I don't think BB tunes are that aggressive.. I think Kooks green cats are made to survive agressive tunes..

Getting ready to install ABS fuse brake disconnect switch in the cabin, which will require me to pull out the top portion of the fuse box under the hood. Will this cause any problems with the computer or any other truck electronics? That will require a trip to the dealer for programming?

Should be fine as long as you unhook the battery first obviously... I wish I had your motivation lol. I just run mine with no ABS fuse so Stabilitrack and traction control are never a problem. It drives great in the winter, no electronics needed.
