Custom Tune for 2011 Silverado 2500HD 6.0L ?

[CMAC780]

I have recently purchased a new Diablo Predator tuner for my 2011 chevy 6.0L, I have not purchased the connector yet. Is there a custom tune for this truck? Should I bother purchasing the conector if theres no custom tune?

We do not provide custom tunes, the tool comes with preloaded tunes. If you are looking for a custom tune you can click on the dealer locater tab on the top right corner. But there is no need for a custom tune on a stock vehicle.
