Ask your doctor if TuneECU is right for you. Side effects include rapid heart rate, sleeplessness, increased acceleration, increased emissions, obsession with tables and graphs and constant tinkering. Unless you have a PHD or at least a Masters in mechanical engineering, you should not even download the program to your PC as it could take over your life. Make sure you advance your timing as far as possible and lean the mixture until constant detonation (increased power) gives you max performance.
