I purchaced the cortex superchips programmer because I had a 2.73 rear gear and was changing it to a 3.42..I started to buy a Hypertech programmer but, the Hypertech will not, I repeat will not except the new gear ratio...Not only does the Cortex except the gear change it has changed my car to a whole new car..The performance option on the Cortex is great..With the gear change and the reprogramming has really changed my car... I HIGHLY RECOMMEND THE SUPERCHIPS CORTEX PROGRAMMER. In my opinion the only way to get better out of a stock engine is to do a dyno tune...Very Happy..

Amazing! Installs easily, and great options. Screen is a little touchy, but you can get around that. On 87 Economy, my gas mileage went up 4 mpg. Ive been running it on 91 Performance the past week...wow! I have 35X12.5X20 and she smoke the tires. Shifting is smoother and when you need to pass...she'll pretty much get up and take off. In 91 Performance, i am still at about 1.5 -1.7 mpg better than at stock. Well worth the purchase.
