 Hey again everyone, it's Cody. Upgrading your car can be confusing, especially if you're brand-new to modifying. In our first video, we discussed what the access port is, what it does, and we learned that a tune is the easiest modification you can make to your car. But now that you have an access port, what's next? Well, there are numerous parts that will incrementally add power to your car, but looking at all of these parts, the question arises, what modification should I perform first, second, or third? And does it really matter in what order I perform those upgrades? The short answer is yes, it does, but every car is different. So while one car may need an intercooler first, another car may need a downpipe first. Installing the actual part though is only half the process. Every time we add a new part, the ECU must be reflashed so that we can make the necessary adjustments to the engine. Now this is crucial because upgraded components change the parameters of what the ECU sees as well as what's physically happening inside of the engine. If the ECU is not made aware of these parameter changes, then it can't make the necessary adjustments to take advantage of what that part can do and the engine won't run properly. Confused yet? Well, don't worry. Through extensive research and development, Cobb has created upgrade paths that maximize power gains each step of the way with both hard parts and off the shelf maps that are specifically created for each part or combination of parts. Each vehicle we support is first brought on to our research and development dyno, where Cobb engineers learn about the car, its quirks, its strengths, and more importantly, its weaknesses or things on the car that limit power increases. Once those weaknesses have been identified, the engineers begin rigorous testing where hard parts are created and installed to find the right order and combination for the best incremental power gains. At the same time, maps are created and tested to retune the ECU so that it supports and takes advantage of each part. From these results, Cobb is able to create the upgrade path of staged packages that have all of the necessary components required to slowly upgrade your car or purchase a full-staged package with all the maps and parts available. So, what exactly is the upgrade path? Take your stock car. Get an access port. Flash car. Car and driver are happy. Get the first stage package. Install hard parts and reflash with the appropriate off-the-shelf map. Car and driver are happier. Get the next stage package. Install hard parts and reflash with the appropriate off-the-shelf map. Car and driver are even happier. And repeat until all the packages are complete. Car and driver are bursting at the seams is static. So what kind of power gains can you expect from your car? Log on to CobbTuning.com and look for your stage package to learn more. And that's it. It can't get much easier than that. Cobb invests thousands of man-hours to painstakingly go through each vehicle, design and test parts and then create maps to support those parts. And we do all of this to make the upgrade process as easy and painless for you as possible with the end goal of making your car that much more fun to drive.
