[Aerovette]

I took the truck to Mardi Gras and it did great. Stupid traffic added a couple hours to the trip, but I made great time coming back.

Interesting thing though.

On a wide open part of the highway, I had a chance to make some time. At 85 it maxxed out and would bounce between 84 and 85 with the pedal nailed. I made a pit stop and got something to drink and when I got back on the road, it went to 98 as I would expect since my old truck was the same. 98 and that was it.

I asked OnStar for a diagnostic to see if any codes were popping up and there were none. I have not checked it with my own reader yet.

I have no idea why it limited to 85 and the internet offers nothing.

The entire trip there and back I averaged 59mph and 16.9mpg.
