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

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
