  • How many revisions does an XCEL Pro Etune Include?
    As many as it takes! usually 2-3 are enough for most mildly modified muscle cars and imports. Sometimes it is discovered during the tuning process that there are vacuum leaks, boost leaks, leaking injectors, failing crank/cam position sensors, oil control valves, etc.. These things must be fixed and verified in a data log before I will send more revisions. I can walk you through these things and offer remote troubleshooting where you have my undivided attention to help solve the vehicles issue, must be scheduled.
