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..
