Is it one that they won't support or re-load for you? Sounds like you have a tune that you think you have no way of getting back on the car. Just remember - the stock tune is also a tune just like any other. You don't have to re-load the stock tune when you change the battery, right? Anything that would ruin your stock tune is something you should worry about with whatever other tune you have loaded up...Many thanks, everybody.
My main concern was the tune.
I will check with the dealer tomorrow.
I cannot afford to lose the Hennessey tune.
Yep, changed out my battery yesterday. Same alarm went off when reattaching cables. Bought new Delco from dealer and installed myself. Total of $140. The battery out of the car had 660 CCA's and the new one had 750 CCA's. If you can get four years out of a battery you are doing good. I changed mine as preventative maintenance as it was working OK. Do not want to be stranded somewhere other than my garage. It can only help and not hurt to change out early before a problem occurs.stations are still stored, but my alarm went off and scared the shit out of me when i hooked the new battery up lol
Is this also the correct battery for a 2014 CTSV? I called Batteries Plus & they said their specs called for a SLI94R AGM to fit my 2014. Any Thoughts?just go to your local batteries plus and pick up Duracell AGM Platinum model SLI48AGM. print the 10% coupon online before you go and they can change it for you for a small fee, but its very simple to do.
