Comparision test between a hypertech and a superchips cortex programmer on my 2008 Frontier 2wd automatic. The 87 octane tests were done in 40 degree weather about ten minutes apart from each other. The 93 octane tests were done in 55 degree weather about 15 minutes apart from each other. The superchips tests were done with the rev limiter raised (hypertech does not have this feature). I also tested the superchips on 93 octane with the timing advanced 2 and 3 degrees but the times were not as fast as they were with the timing at 0. Disclaimer: Your results may vary!
