Getting Better Throttle Response in a Mustang GT

Improving throttle response will give you even more control of the car. When you mash the pedal you want to feel that power instantaneously.  If you tackle all of the areas I’m about to mention I can guarantee your throttle response will improve. If you feel your Mustang isn’t quite as responsive as you would like it to be then here are the three main areas to improve on that affect throttle response:

  • - Tune

  • - Engine Modifications

  • - Drivetrain


Getting the car tuned is probably the best place to start. A custom tune can directly change throttle response especially in drive-by-wire cars. Drive-by-wire refers to the flap on the throttle body being electronically controlled as opposed to a cable like the previous models. Getting your car tuned will also net you some decent horsepower and torque and it will allow you to get the most out of the performance modifications that you’ve already installed.

You can purchase a handheld tuner and either have tunes preset when you order the unit or you can take it to a local performance shop that if familiar with tuning cars, mustangs in particular, with that software. A tune can also change shift points and how firm they are in automatic transmissions and will aid with throttle response as well.

Engine Modifications

As far as aftermarket parts that will help increase your throttle response you have quite a few options. Here are some less complicated parts for you to get started with:

I personally think one of the easier and cost efficient ways is to add a throttle body spacer because this  causes the throttle cable to be stretched a little bit. If you have another method of tightening the throttle cable then, at your own risk, try it out. Next, I recommend upgrading the throttle body and plenum to a larger diameter. This will allow more air in, increase throttle response, and net you some horsepower and torque. An aftermarket cold air intake will definitely help as well. The last upgrade I mentioned is to replace the coil packs or coil-on plugs with a high performance product.  They produce more spark which will burn fuel more efficiently,  increase horsepower, and could also increase throttle response as well. All of these modifications combined together should deliver your power much faster than before.


Another way to improve the response time of your car is to shed some rotating weight. By doing this you will allow the car to rev faster and help the more power reach the rear wheels. The most common way of doing this is to purchase an aluminum flywheel and/or an aluminum driveshaft.  You can also switch to a higher gear ratio in the rear. The most common upgrades are 3.73 or 4.10 gears and they will help the car accelerate faster from a dead stop as well as help get the car into its power band faster. The speedometer will have to be recalibrated after changing the rear gear ratio.

Although it is quite more technical than the other modifications I have mentioned, you can also consider changing the gearing of the transmission.  This will allow your car to react better in different RPM ranges, especially when the car is in its power band. It takes a bit of research to figure out which gearing is best for you.

2015 Shelby GT350R & GT350 Production & Pricing Numbers Released!

The S550 Shelby GT350

Ford has officially released the 2015 Shelby GT350R and GT350′s production numbers and it will have quite a few people upset. Ford has also given us a breakdown as to what certain options are going to cost on the new S550 SVT Shelby Mustangs, cuing us in as to what we can expect MSRP to be.

2015 Shelby GT350 Production Numbers

While both the GT350 and GT350R are incredibly desirable to any automotive fan, it is certainly the GT350R that speaks to the inner-racer in all of us. Unfortunately, not of us will be able to get one as the production numbers will be incredibly low. How low you ask? Ford says that they will produce only 37 Shelby GT350R Mustangs in 2015.

The reasoning? As Jalopnik pointed out, it is because they are paying homage to the original 1965 FIA-homologated Shelby GT350 competition Mustang production numbers. Those numbers themselves are a point of contention for Shelby aficionados. According to Shelby, there was 2 prototypes and 35 production GT350′s created in 1965. However, VIN records show that only 34 1965 Shelby GT350′s received VIN numbers. Ford has decided to produce 37 in memory of Carroll Shelby for the 2015 year.

If you did not plan on getting a GT350R and only desired the 2015 GT350 Shelby, the news doesn’t get much better. Ford announced they will only create 100 Shelby GT350 models for 2015. That means that 137 GT350R and GT350s will be made in 2015.

However, there is no need to panic as this is only for the 2015 Mustang model year and not the 2016 model year, which Ford plans on bumping up production for.

2015 Shelby GT350 Price

Ford has given us a small glimpse into what we may expect in terms of MSRP price for the new S550 Shelby GT350. Broken down by Mustang6G, the prices for the following options have been released:

2015 GT350 Option Pricing (MSRP):

  • Tech Package = $7500.
  • Track Package = $6500.
  • Navigation = $795.
  • Painted Black Roof = $695.
  • Triple Yellow = $495.
  • Over the top stripes = $475.

2015 GT350-R Option Pricing (MSRP):

  • R Package (over base GT350) = $3500.
  • SVT Touring Package = $3,000.
  • Navigation = $795.
  • Painted Black Roof = $695.
  • Over the top stripes = $475.

While they have yet to announce the official total price of the GT350, we can already start adding up the various options. Combine that with the 50 year anniversary for the GT350 as well as the limited production run that is planned for 2015, we can expect the price to be in the ballpark of $50,000+.

What are your thoughts on the limited production 2015 GT350 run? Does it add to the heritage or does it only drive up the price?
