So you’ve been researching and reading up on ways to get more out of your vehicle, and in an age of ever increasing computer control, this is becoming more and more common of an option. Manufacturers put limitations on the vehicles for reliability, emissions, and future proofing reasons, but, what would it truly be like to push these boundaries? So that you can truly push it to the max or get the kind of fuel efficiency or response from it that you would really like to have? Well let’s take a look at what is available and what it can do for you. There are performance chips, performance programmers, engine management systems, and throttle controllers. It can seem overwhelming to know where to begin. Check out our Performance Programmer Buying Guide

"I added new tires and rims to my Yukon XL. It was driving awful until I used the Cortex Programmer. It allowed me to set tire height and choose the 87 Octane tuner as well. I took the speed limiter off too. It shifts smooth and gets better gas mileage than it did before I put the larger tires on. It has much more power and really drives much better. Thank you Autoanything and Superchips. Without it, I would have went broke putting gas in the vehicle or would have had to sell the new rims and tires." —Christopher T from Charleston, WV bought a Superchips Cortex Programmer for a 2007 GMC Yukon XL, 5.3L V8.
