I have a 2006 v6. So I've done the basic bolt ons pretty much. Things I've done all the basic b******* you find all over the Internet said over and over again.. I'm looking to get a little more umph. and maybe some of my list of mods will give some of you guys ideas so it's a win-win.
I'm not looking to hear by a V8 I get it. I realize turbos and blowers exist but they're a little out of my price range.

Things things I've done that I can remember:

cai, headers, cat back dual exhaust, underdrive pulley, bama tune, 70 mm throttle body, lower control arms, upper control arm, Accel coil pack and performance wires, 3.73 gears, strut tower brace, lowering springs. Mph Short throw shifter

this is pretty much all I can think of and I'm sure I miss something. But you get the point that I've done a lot of bolt on mods. I'm wondering what else I've missed.

Weight loss:
​​​​​Rear seat delete, Ford racing front bumper support,

Things I want:
aluminum driveshaft, Auburn limited slip differential. Throttle body spacer.

and that's all I got I'm just wondering what else I can do for modest horsepower gain. Thanks for reading

That's about it. All of that wasted on a V6. As the commercial says "You could have had a V8" for that much in aftermarket stuff.

Without going FI, looking into more weight reduction. Lighter wheels, AC delete, carpet and sound deadening...the list goes on and on, and some removal is free

Are cams considered "bolt-on"? Although from what I've seen about working on a 4.0L SOHC, I don't think it'd be worth the amount of work for the limited return on investment of time and $$

FI or motor swap.

Save your money on the spacer - all it does is lighten up your wallet. This isn't a carburetor car where a spacer can make a difference. The air and fuel are mixed in the cylinder. And moving your throttle body a half inch does nothing.
Save your money on trying to upgrade a 7.5" rear end too. It is cheaper in the long run to simply swap to a 8.8" rear end, and stronger too.

Other than nitrous, or heads and cam, there's nothing else you could do for a noticeable power bump (even if that was a V8).

The Mustang that was the most fun to own was my 2006 convertible with the 4.0 and Xcharger Xtreme supercharger on it.

Unfortunately Xplorer Xpress closed up and the owners retired. So you either have to find a used one or build your own turbo system or get a centrifugal supercharger (Procharger is one and can't think of the other one for the 4.0)
Edit: Vortech, just remembered it.

Get educated and build your own turbo kit.

Thanks for the input

Against all advice...

I installed the shaftmaster ADS, Yukon posi, throttle body spacer and recently bought a vortec SC.
The car runs much smoother now with more pronounced response.
Ultimately, I am very happy with the outcome of the mods.
