Bolt ons.....see cliffyk's post " the beginners guide to bolting on power " I believe is the name of the thread. But you can add things like: throttle body, plenum, CAI (looks mostly), exhaust, tune, etc, etc.

Gears is one of the best "bang for your Buck" mods

4.10s, mid pipe, catback, pullies, cai, plenum, tb, tune up, suspension, wheels and tires, MPT tune. Those are your traditional bolt ons and will really wake the car up. Don't be expecting to keep up with F bodies or newer Mustangs though.

Any engine, drivetrain, mod/upgrade will make your car accelerate faster.

Nope, plenty of "no return" mods.

Like the idle air control mod, EGR delete, valve cover breather mod, and forged internals, and such mods like that? Educate me.

Axles are kinda nonreturnable, fuel if your not max duty cycle for injectors or pump. But almost every other mod I'm thinking of is returnable some way.

IAC mod is just for drivability and I never had to do it. Egr delete has 0 performance benefit, valve cover breather mod is not going to get you anything and is not required if you are na with a good pcv system and forged internals are if you need more than 450rwhp. Lots of snake oil mods out there. Also triple check any info on the Internets. Way too many info recyclers and internet racers out there.

Makes your Rpm's drop faster, it's also one way of fixing hanging rpm's. Like Scotty said helps drivability.

Copied from the wastelands of the internets...

This is a super simple modification that you can do to your 99-04 Mustang GT 4.6 2v. With this mod you will create a new IAC gasket to fix the annoying RPM "hang" that stock GTs have. Have you ever reved up your engine and had it take forever to get back down to idle? This is what this mod will address and fix.
PROS:
- RPMs will return back down to idle faster. Makes for cleaner sounding revs without the annoying "hang".
- Engine braking effect will be present. Meaning; when you let off the gas, the car will actually start to slow itself back down instead of coasting.
- Makes the exhaust have the "gargle and pop" sound like an old hot rod when its on the down scale of a rev.
CONS:
- A "hissing" sound may be heard from under your hood when your standing near it. Sounds like a large vaccum leak. I believe this occurs because of the large amount of air restricted to the IAC by this mod.
- The vehicle may not be able to pass certain local emmisions tests. The reason our cars hang the RPMs in the first place is because of some emmisions crap Ford did. (Just keep your old gasket if you have to smog)
- You may have to re-learn the car a bit as far as shifting (manual trans. cars). The RPMs will fall faster and require you to shift a little sooner then normal.
- If you drill the hole too small, the car will not idle correctly. (Just make the hole bigger!)
As you can see, the Pros far outway the Cons, so go get your materials and tools and get to work!
Tools:
- Gasket Material: You can get this at any parts store like NAPA, Auto Zone...etc... It comes in a sheet, just tell 'em you need about 12'' x 12'' of it. Or, you can even use tin or thin rubber, I used gasket material to insure no air leaks.
- Socket Wrench (A socket extension is recomended)
- 8mm socket
- Ball point pen
- Drill
- 3/16'' drill bit (or even a 3/16'' punch may work if no drill or bit is available)
- A cardboard box
- Common household scissors
-1. Remove the PCV hose so you can access the lower IAC bolt, and remove the (2) 8mm bolts holding the IAC to the upper plenum. Remove the gasket. IMPORTANT: Keep the gasket somewhere incase you ever want to reverse this mod and/or you have to get a smog check!
Thumbnail Image

-2. Place the stock IAC gasket on the sheet of gasket material, and use a ball point pen to trace the stock gasket onto the sheet of new gasket material. Make sure to trace out the bolt holes on the sides of the gasket as well. Mark an "X" in the center of one of the large holes.
Thumbnail Image

-3. Using common household scissors, carefully cut out the new gasket following the lines you traced.
-4. Set the new cut-out gasket on top of a cardboard box. This will make it easier to drill (or punch) your bolt holes and center hole through the gasket without it ripping in your hands. Drill out your bolt holes using a 3/16'' drill bit, you may need to make a circualr motion with the drill in which it will "round" out the holes a little bit more. Test the sise of the hole by trying to push one of your 8mm bolts through the hole. If it doesn't go through, round out the hole a little more until it goes through with a snug and tight fit.
Thumbnail Image

-5. Using the 3/16'' bit (or punch), drill a hole straight through the little "X" you made in the center of one of the large holes. The size of this hole will determine how hard your revs fall or if your car will stay running at all and is the whole purpose of the mod. I've heard of people using 5/32'' bits for the IAC hole, I tried a 5/32'' bit and my car would not hold an idle and would die as soon as I let my foot off the gas, so I stepped up to 3/16'' and all was well. If this happends for you with the 3/16'' bit, then keep stepping up the size until your car runs properly and holds a nice idle.
-6. Now put the IAC back on with the new gasket (make sure the hole you drilled is on the side of the large hole in the plenum). Re-connect the PCV hose. IMPORTANT: Do not over-tighten the 8mm bolts back into the plenum!
-7. Fire up the car and check the idle. Make sure it holds an idle around 750-950 RPM or so, basically checking if it is idleing ok. Wait for oil pressure to build...etc... and give it a nice rev. Check to see if the car revs up clean and falls back down to idle with no problems. I've heard a few people talk about how this may affect a cold start, but I did this mod out in 18' F weather and the car fired right up. It won't go into a high idle, but it will idle never the less...This sounds like a lot of work but its simple... ENJOY!!!!

I got two of these pipes, one with the iac mod and one without the iac mod. With the iac mod It threw my a/f ratio off quiet a bit and I didn't need that when spraying nitrous so I just switch them out when I'm about to race and when I'm done racing.

when my ac is on, the idle hangs more, like if im coasting 5mph in neutral, and finally stop, my idle goes from 1200 to 700, and when that drop happens, i hear a faint pop gargle thing like this suggests. is that what they are reffering to? mines currently not modded.

Sorta yeah. That 1200 rpm idle while coasting at 5mph is going to change to being 700 rpms if you do the iac mod. It makes it so that your engine becomes better at taking orders from your right foot.

If I were to upgrade the plenum on my 03 GT, would I have to update my MAF sensor also? I don't want to do a throttle body or CAI because for the most part of what I have read here you don't need either of your still NA. My current state is drop in K&N due to being able to reuse it. And I got it terrible cheap. And SLP cat backs. I read the plenum gives better throttle response. I am going to have the car tuned here locally with the SCT tuner and they also take it for a drive and data log and correct from there. I'm also going to have the transmission flushed and new filter then tuned also. After that they are going to install 3.73 years and a GT 500 diff cover. It's on stock springs and shocks with cobra rims. So in short what about that MAF sensor?

You won't need a new MAF unless your running boost
