It was about 65 and sunny outside and I had just got done washing/waxing it and figured I'd go try the Gtech for the first time on the SRT-6.

So I took it out to some of our country roads in the corn fields and ran it...!
I did four runs, two with the Gtech Pro and two with my Beltronics Vector Pro (same as Gtech but much nicer with more features).

Run one was a 12.9 @ 112 mph w/ 1.9 sec 60 ft and 4.70 sec 0-60 mph.
Run two was a 13.0 @ 110 mph w/ 2.0 sec 60 ft and 4.75 sec 0-60 mph.

Then I pulled off the road and switched to the Beltronics and ran it again...

Run one was a 12.9 @ 110 mph w/ 1.97 sec 60 ft and 4.67 sec 0-60 mph.
Run two was a 13.0 @ 109 mph w/ 2.08 sec 60 ft and 4.72 sec 0-60 mph.

So, I'd say they are probably pretty close to being right.
I did spin the tires a little each time on the take off, which was very hard not to do, even when leaving at idle like I was doing.
Now I just need to take it to the track to back up the times, I have a good feeling I will, because traction is usually better at the track compared to the street.

I've used the Gtech on my previous SRT-4 when I had just a few mods on it, and it showed me running 13.7 @ 105 w/ 2.2 sec 60 ft times...the very next day, I took it to the track and was running 13.45 - 13.6's all day.

So we shall see what happens with the SRT-6 at the track, because I know it hooks up better then any car I've ever owned on the street.

Thought I'd take some pics while it was nice and clean.
There is more in my gallery of the engine and stereo system too...
