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 can always go on dynojet to get better numbers lol

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.

There is a switch but it doesn't fully disable it. Doesn't completely disable it on the older trucks either. I had the same issue with my Trailblazer SS and Silverado SS trucks back in the day. If you make enough power, you'll notice...

That explains why I've seen some high hp trucks with their dash lights on. Didnt make sense they Couldn't tune it out so now I know. I've hit this weird bog before but didn't know what it was. I need to step my game up lol..

It's very popular trick within 4x4 off-road community on many different trucks as well.

Do they have an AWD dyno there, with the ability to tune it?

yes

was looking at the lifter guides today some of descriptions say won't work with AFM, is there any difference in afm and non afm guides?

Are you talking about the plastic lifter trays? Buy the non AFM ones, the lifters are different so I'm sure the trays are as well. They are so cheap it's not worth trying to reuse old ones.

*Use an OEM LS7/LS3 tray for non AFM cars/trucks
