Question MPH and MPH ?'s

I thought I would like to start a new thread to see what everybodys elses inputs are. The questions are:

1. Whats the max speed you have gotten your truck up to and w/ what on it?
Mine is 128 with an Edge Evo., K&N cold air kit, custom exhaust and runnin on premium.

2. Whats the best and worst and average mpg you have gotten with your truck?
Mine is 19.5 babying it and 13 running the hell out of it, and once I got 9 when pullin a trailer, average is 14-16 city

What's everybody elses input on these questions?

Fastest I've had my truck up to is 110 mph before the wife said "alright that's enough". All the mods in my signature were done to the truck at the time.

Best mpg's I have seen with my truck was 19.4 and that was 90% highways miles. The worst I have seen is 10.7, but that's because I live in Hawaii now and all the traffic out here is stop and go and lost and lost of stop lights.

Fastest I can't say. See the Avatar I was past that on the night my wife got in her crash. I was walking off from a Monte Carlo that was headed to the same crash. Best MPG was 22.5

Im past the "HOW FAST CAN YOU GO" phase in my life. My 07 5.4 SCREW is averaging 17.6 in mixed driving. Thats will only the Gotts mod on my intake and nothing else. But i'm going for duals and a tuner very shortly.

I got mine up to 100 mph but decided to hold off(I've already got two tickets in one year). It could have gone more but I didn't push it. thats with no engine mods.

as far as mpg, my worst was 10 mpg in stop-and-go traffic, best was 18 or 19 on the highway, I usally average 14-16 mpg.

Best mpg's - 20
Worst mpg's - 9

Fastest in the '06 was 90mph, before I realized how fast I was going. Was passing a car on the down side of one of the passes here in CO.

Not nearly the fastest I've been, but was plenty fast in the 150.

nice, I stilll haven't been able to break the 128 mark, and I have never heard of hydrogen injection, at least not for my truck.
