ecutek tune for sprintex
 

I have a question about the ecutek tune. Does the ecutek tune need to be downloaded before the supercharger install so when completed before initial crank or install charger then down load ecutek before initial crank. or does it matter before or after. ( I know not to crank until the tune is installed) just curious if it mattered? I know the install tutorials say disconnect battery during installation, just didn't know if I downloaded and then disconnected battery if upon first crank I was going to get a check light. As a side note any of my other mods I have never disconnected battery was always careful. Is it necessary to disconnect battery? Thx in advance Steve

It should crank and idle on stock tune just fine.

Wayno good deal Thx bud
