How much more HP and TQ do you think you'll get from the new TB and tune?

Can't drive the car now for a week or 2 though, since the intake tube is off being smoothed and hydro dipped

JDM has told me in the past that a Ford Racing twin-65mm TB would add about 20 hp/20 ft-lbs but Pete wasn't happy to see as much timing as they have into my tune. His opinion was that it's too much timing for the Coyote, he would've backed it down 1-2 degrees for safety's sake.
Also, JDM's tune has a rev limiter of 7400 RPM I think, and that's a lot of movement on the stock non-forged rods, especially with 9+ psi of boost pushing into them.
He prefers a rev limit of under 7,000 RPM, and I'll probably ask for something around 6800, again for safety's sake.
That's plenty of RPM.
It's not a built N/A motor, no need to rev it to the moon.
This time it's gonna be Pete @ Performance Dyno in Loudon NH, about 45 minutes North of me.
He's done thousands of Mustangs, is well known around here for the safety of his tunes, so I want the most power my mods will provide, but ultimately I want the safest possible tune so I don't pop the engine.

Really have no idea.

Good luck and keep us posted bud!
Drove all over the place today. A good 4-5 hours worth. Felt so good. Managed to get a couple pictures. So many nice cars out today. Was driving down the highway and had to turn around.

Your car and the wheels look gorgeous! What size tires do you have on them and what suspension? I'm planning on getting new wheels by summer too, and I was definitely considering the DF5 or the MMD ones by AM. I really love the 5 spoke concave look.

Rear is still up high, but I did bring it down a bunch.
I want to do some rear suspension work on it and it was actually too high for me to easily be able to reach, lol
