Travo

So I have the 2.7 I4 in my GMC Sierra and I’m getting around 30 mpg if don’t speed everywhere I do have intake and exhaust and it blew my mind how much power it has I am looking to tune it to get more out of the turbo but I hit 25 mpg across the board I’m a v8 person always have been but it did blow my mind 10 to 15 years ago no way I would have thought about being in the driver seat
