So I had enough of my 15 Silverado 5.3, 16mpg. I had a 02 CC duramax that got better mpg. I finally found a 17, 2wd grey Colorado that was just sitting there begging for me to take it home. I like it, its working out. I hope to have many years and 400K before its over. I do want to get as much out of this truck as I can. I hope to find a tune that gets me closer to 40mpg?????? I have to believe that someone on here can do it.

Welcome. Didn’t know they made the diesel ones in 2wd. Don’t know of anybody getting in the 40mpg range but dream big dude!

Are you looking to tune it yourself or buy a tuner? There are a few of us tuning them like myself, and there are also a few good options from vendors who offer remote tuning.

GDE seems to be a popular choice as far as a vendor to buy a tune from.

If you choose to do it yourself you need either EFI Live or HP Tuners.

So far so good, love this truck. Finally got thru a tank, 26ish, that's with filling up to the top. It was more than the dealer did so I'm waiting on this next tank for a better reading. The dealer said they willed it up???? Don't know about tuning just yet maybe wait a bit till I get a few miles on it. I think like my other diesels there is room to grow
