I filled mine up with E85 last night. Drove 50 miles and could not tell a difference in power or mileage. I never tried it before and thought I would try one tank. It was 50 cents a gallon cheaper. The town I live in does not have an E85 pump so I doubt I will buy it again.

Only after one month of ownership, I decided to install a 1.5" leveling kit to get rid of the forward lean. I still have a slight rake in the rear, but I prefer that look over the previous. I took way longer than the average install time, as I ended up breaking a lower shock bolt and had to drill and cut it to get it out, but I got it done. It was a good bonding opportunity for me and the truck. haha.
I appreciate those of you who share your knowledge on this site. It has been a big help so far.
I couldn't find a perfectly level parking lot for the pictures, but I tried to be consistent. Leveled Tahoe Before.After2.jpg

I'm hating the way this Flowmaster Thunder kit is looking. I'm thinking about cutting it where it isn't visible. Ideas?
I'm thinking cut where it connects? Is that about where the factory resonator sits?

I did 2 fillups with e85 to make sure that I was running 100% e85 and I never saw more than 11.9 mpg combined. I normally get 16ish combined driving.

I'd rather do the 93 tune with my bully dog than run the e85. It's roughly the same power, imho, and it holds 4th gear longer on the highway without downshifting, which is where the mpg incease comes from for me with the 93.

The e85 burns too quick. It it was 1 or 2 dollars cheaper, yeah. At .30 or .50 cheaper, the gas station is getting rich selling you 15% gas.
