Upgrade suggestions.

[Joey.2500]

I am new to the deisel seen. I have a 2014 Denali HD and I want to start upgrading it. I would like to get some advice on what will be the best setups that others have had the best luck with.

What are your goals with the truck?

Lift pump regardless of what you do at a minimum if not a CP3 Swap.

I would like to get my fuel mileage up some but I defiantly want to get the power up. I have a shop by me that will tune it but it would be all out and he said it would not be good if I wanted to hook it to a load. I don't want to be limited I want the ability to Change it when I want to. I have heard EFI live.

There are good reputable tuners out there that will tune for your needs…not just all out.
