So I thought I'd try and record some data on my holiday trip in the SRT. I was not looking to set any records here, just more for my information and maybe some of you will find it interesting as well. I kept track of how much gas I put in at each fillup and my miles traveled. I also had a GPS that gave me overall average speed, moving average, max speed, total time, moving time, and stopped time. I tend to drive +3-7 mph over the speed limit but I'll tuck in behind someone going faster if I can. This is on the stock tune as the octane grades vary across the state and I don't want to deal with changing the tune. I probably had about an extra 200-250lb in the trunk as well.

so the average isn't that great but I had to go though a lot of small towns with lights, single lane highways where I had to accelerate to pass people, had a little fun in the car, and drove a little faster than I planned on.
