Hey, so what should the gas mileage be on an LS turbo? Before, I was getting about 18mpg and then I got it re-tuned with Crome. The mpg improved, but I still think it's pretty bad. The last time I filled up, I only got 23 mpg and I pretty much kept it under 3000 RPM. What's the deal??? Do you think it's the DSM injectors? I noticed the bad mpg happening around the same time I got the DSM injectors. Like I said, I've been driving like a granny and trying to avoid the turbo, but I'm still getting 23 mpg. It should be getting at least 25 mpg with some moderate use of the turbo, I believe. I would appreciate your input. Thank you.
