More questions for the pros.....
I have a 2011 Suburban LTZ 4WD. It has the 6 speed tranny with the 3.42 rear. I tow a 6,000lb camper. My 2007 Suburban LTZ 4WD did a MUCH better job towing. The 2007 had 3.73 rear and 4 speed tranny. (i think it was a 4 speed). My gas mileage in the 2011 is worse than the 2007. The 2011 has less than 15k miles, whereas the 2007 had almost 90k. I ditched the 2007 in hopes that the 2011 would be a better pull. So far I am VERY disappointed. I've tossed around the idea of swapping gears, re-tuning, or both.
I'm just looking for some honest opinions and any help I can get. I've tried reading up at other chevy forums but you get such a mixed bag of answers and opinions. You guys were always right when answering my trailblazer questions, so I figured I'd pass this along to you guys as well.
I hope everyone is doing well! Thanks in advance for any help you have to offer!
