Here is my experience with the Aftermarket 62mm Throttle Body, I have dynoed my 2005 Mustang GT with an automatic trans. No other mods other than a K&N Aircharger. First Run - Stock GT 250 HP Second - Stock GT w/CAI 263hp Third - Stock GT w/CAI and TB 269hp fourth - SCT Tune w/CAI and TB 271hp 280Tq Fifth - SCT Tune w/CAI Stock TB 272hp 282tq
If you are not planning on tuneing your car to keep from voiding your warranty then you will get better performance and throttle response from the K&N CAI and Throttle Body. The reason why I choose these two products because they advertise no tune required. After reconnecting the battery and putting the car back on the dyno the third time, the computer was able to compensate for the increased airflow and adjust the Air/fuel so as to not run to lean.
If you plan to tune the car, then I suggest starting with the JLT CAI and Underdrive Pulleys then a Axle-back Exhaust, No HP Gains But they sound Damn Good. With a tune, there are no advantages to the 62mm TB
If you want to get more aggressive, install headers, High Flow Cats or Cat Delete, X-Pipe, then put on Charge Motion Delete Plates and Electric Water Pump. If you are real dareing, Get a little Nitrous Oxide.
If you "Just Say N2O to Nitrous Oxide" Then Go Wild and Get a Supercharger. This is a little bit out of my league so maybe some one can post the ins and outs of Superchargers.

I've heard once that the computer will adjust to simply a CAI, but mine threw a Check engine light and the dyno showed a drop of about 26 hp and 36 trq(in high altitude also). Anyone who is new at this should buy the Cold air kit along with the tuner.

Make it breathe better. I did Intake, tuner, longtube headers, and exhaust and picked 30 horsepower, and the car still idle's and runs just like it did from the factory.
I have the CAI and Tuner on my '05 GT. I had it in the shop yesterday and they told me it's not covered under my warranty. What they didn't realize is my buddy owned the car before me and put it on and so when I went to the dealer to buy it, it was covered under my warranty because it was on the car when I bought it. I don't know if it would affect your warranty or not.
I'm not so much worried about that particular part, as much as the warranty for the whole car if something totally intake un-related happens, will the warranty be good... ?
Let's put it this way, if ANYTHING you do to your car... ANYTHING at all... causes a malfunction, breakage, etc. that malfunction or breakage is NOT going to be covered by your warranty; and you're on your own.
Of course, some dealers will overlook somethings... BUT that's dealer specific. Ford HQ will tell you to pound salt.
The service manager at the dealer I bought the car said the K&N was ok because K&N will help back your warranty. If you add a tune, remove it before you take it in for warranty repair.
I have been told that when you tune your car it puts a "flash" date on the computer. If you put the stock tune back on your car then the dealer can see that you have done something to your car because the "flash" date will be different than the original. For this reason I have not yet tuned my car. Can anyone confirm?

No time stamp, the only thing that the dealer will see is that the history is cleared, like the battery was disconnected for a while. these computers have no external time /date stamps all timing is internal only.
I reflashed mine before i took it in for service on a CEL code, they called me asking if the battery died because the history was gone. I told then I disconnected the battery to clear the Check engine light to see if it was a fluke, they just said ok.
I just bought my SCT X-Cal2 tuner w/3 tunes and have one question. I installed the K&N CAI and this wasn't listed in the choices of MAFs. So I chose the C&L CAI and went to drive my car and as soon as I punched the gas the car hesitated and coughed and then I received a "Fail Safe Engine Mode" message in the LCD. So I went back and reset it to "Stock Airbox" and it runs fine now. My question is should their be any other adjustments I should do to get better performance? Like add anything to the WOT setting? It was recommended to add 5% to the WOT but I was not told which way to add (Leaner/Richer)? Any advise is greately appreciated.
BTW, I am currently running her on the 87 Octane tune.

As a newer member and as you can tell one that has not taken the time to post photos of my GT, I did want to relate some good experiences with basic mods.
Some thought on baick mods.
The Predator tuner was a a great aquisition. I have had mt GT since November of '04 and waited for options to hit the market and prices to come down (not much luck there) but I digress. The predator has been great, I've tried the 87 and 91 performance tunes so far.
I just added the Airaid CAI and retuned to the 87 Octane Perfomance tune (gas prices played a role there) to check out the performance. That combination made a noticeable difference in throttle response and it sounds great. I know many here have used the C&L CAI and retuned for that mod, but I tried the Airaid system on the recommendation of a friend at a local shop here, and I really like it. Installation was a breeze the design is solid. I can removed the MVT restrictor and retune if I choose to later. I like having the option.
I have aslo done the aluminum rear windo louvers (from MRT) and the side window louvers. Had the side louvers painted but kept the satin black on the rear. The hinged rear window louvers are easy to install and the hinged design makes them easy to handle when detailing.
But my first mod was custom cut side stripes saying MUSTANG GT followed by wheels and tires. Stayed with 17 inch but went with wider Cobra wheels and tires. Going for that chrome retro mag look. I also added sequential turn signals, a blackout panel on the back between the taillights, and black SVT tail light trim, and Viper Alarm System.
So I guess it all depends on what you are most interested in. I like things I can do myself, and easily. To date I have never had any touble with any of the mods I have done and I am thinking about what will be next!
cwall583 sounds like a nice car and you have had plenty of time so get on it and lets see some pic's. Have you tryed the 93 tune out yet I thought it felt alot better then the other 2 at clearing up some throttle lag. (Auto)
I got mine about the same time 10/20/04 and the mods went like this.
1. C&L CAI and Preditor <--would love to trade that for a SCT2 2. Steeda UDP 3. Mrt-Direct back and side louvers 4. Borla catbacks & Steeda 1.5' drop springs 5. Centerline Rims and Rubber 6. Short antenna 7. Steeda strut tower brace 8. Hood Struts <-- So many people want to look under the hood I was just waiting for the stupid prop to fall and cut someone's hand off lol
I would love to find a good ducktail spoiler that will cover the factory hole in trunk lid and a functional hood scoop that I like and I think i would be happy.
