Single turbo kit for better fuel mileage

Sheehan6 · May 17, 2021

I have a 2015 Sierra with the 5.3. I recently picked up a slide in camper and I want to boost my fuel economy as it is god awful when the truck is loaded. I’ve been looking into turbo kits and I’m just curious as to which ones people have had good success with in this application. I’m not looking to be fast, I just want a cheapish solution to not owning a big diesel burner. I have a list of key questions I’d like some insight on.
-What turbo kits should I consider?

-What mods should I consider to prepare my engine for boost?

- Would the gain in fuel economy and price of higher octane fuel needed level out?

-Can I run the stock 6 speed transmission with 100+ more horsepower (6L80)

Thanks guys

By the time you're all said and done, you will waste a ****** ton of money and time. And you will not get any better fuel economy and probably tear up your trans. Your answer is to buy a diesel truck.

I use to try that type of logic on my wife years ago when first married. One day hot rod magazine showed up. Gee thanks I said. No it’s for me she said. I was so busted. She took over the check book. I was put on an allowance. That forced me to budget and fix up and sell cars. It also made her a car enthusiast. All from hot rod magazine.
