ECM tuning is a very generic term used by many people. Tuning is best described as altering the original content of a stock OEM file. This must not be confused with the term "flashing" or "programming" which most anyone with OEM software can do! The first step is acquiring the stock original file, then by using either OEM engineering or equivalent software you can make changes to the program. After those changes are made we can now flash it into your ECM. What largely sets us apart from most "tuning shops" is the ability to make these changes to the stock original files ourselves.
