Engine Management
One of the most important areas to consider especially if you are performing any sort of engine modification that will increase your boost levels, horsepower, and torque. If you try to perform modifications without a proper tune you will injure your engine. If you move to another state and have a tune suited for your elevation levels and your new state has a higher or lower elevation, you will need to adjust. You need to make sure your air/fuel ratios are within a safe strike zone under load. Failure to have a proper and professional tune and/or engine management system could result in you becoming familiar with engine rebuilds and replacements.
