2016 Chevy Silverado LTZ Z71

I really don't know what to expect from a custom tune. I am pretty happy with the canned tune. It took a few days to get used to, but its worth it IMHO. I'm assuming a custom tune will find a little bit more power out of the mods I've done. I can't see it being that big of a difference though.

Well out of nowhere, my truck wouldn't start. Completely dead

Had to jump it and went and bought a battery this morning

The truck starts SO MUCH better

I bought:

Die Hard Platinum AGM
Size H7
850 CCA
1000 CA

Stock CCA I think was 730

20% off coupon and a $22 core..........$172 after my core return and coupon

I was worried the H7 size would not fit, since a stock appears to be an H6

Fit perfectly........just was a huge PITA to swap the batteries out, due to the location and that distribution center ontop

Not sure if the new 1500's are the same but heres how I upgraded my '11 2500 gasser.


Die Hard Platinum AGM
Size H7
850 CCA
1000 CA
51.8 lbs

Die Hard Platinum AGM
Size H6
750 CCA
960 CA
45.6 lbs

Either battery will fit.........but I went and gambled with the H7 size and it fit perfectly


Seems like the 5.3L could get either a 150amp or a 170amp alternator

My trucks has this P/N 23487089

This number equates, I believe, to a 150AMP part
