Hi guys and gals

My user name is Vern829, my name is James Schronce.
I live in NC close to Hickory. I have a 2013 Caprice 6.0 6l80 I am currently working on and I have several Chevrolet trucks.

I am currently looking for help for my wifes 2004 Suburban 5.3 4L60E 4X4.
This truck is completely stock, I am looking for help or a tune to cleanup the stock tune for better performance and fuel mileage.

We are going to drive it to Branson MO. in the near future and would like to help it out some.
I am thinking about putting a CAI on it.

I looked it the Tune Repisitory for a modified stock tune but did not see anything.

Anybody have a tune I can lookout or sugestions on what would help the stock tune out?

Any help would be greatly appreciated.

Thank you

James ( Vern829)
