I am an owner of a 2011 Chevy Cruze RS with Turbo 1.4L.
I just had my turbo charger replaced last week at around 71,000 miles and received my car back this week.
On my daily commute I travel on a 70MPH highway and use my cruise control for the duration of the drive. I don't 100% remember where my RPMs used to be before the repair work was done, but it is cruising at about 2,700 RPMs and i feel that is much higher than it was in the past. Although, I'm not 100% sure where it used to cruise at; I was hoping to get some input from some of you guys to see if I need to bring it back into the shop or if this was a normal cruising RPM.
My 2012 ECO MT runs right around 2300 RPM at 70 MPH. BrandoFisher's LT is running at 2500 RPM - automatic and same model year. Knowing the final drive ratio was increased from 2011 to 2012 OP's 2700 RPM sounds about right.
