can't wait to get home and get mine installed on my truck!

 

SC's are great, I noticed a big diff in the tow/haul mode, I could cruise at 100k and pull out and pass going up hill with a 12ft covered trailer loaded, moving the kid's stuff, 4.7l.
Do you have to reload "your" tune again if you take the battery ground off,or change the battery?

 

no, the tune is "burned" into the PCM, just like the stock tune.
