i have the prior version and it was pretty good. as long as you calibrate it correctly it is fairly accurate. It was right on with its hp estimates. Plus the coolest thing is you can download the runs to your computer and analyze them using special software from g-tech.

its nice but the one thing about it is that i just don't use it that much.

 

i want one

 

For about 20 bucks you can buy the previous model on e-bay. Not as cool looking, but having used a Vtech 200 (and now this Gtech) for years, you don't really want to permanatly mount it.

Gee officer, I wasn't speeding, don't know how I got this device on my dash...

I have that model but havent used it yet. I need an accurate weight of my vehicle with the wheels on it. I plan on custom mounting it inside the ashtray area.

I've been wondering about those. I'll probably eventually get one to try out. How hard is it to accurately calibrate it?

I'm reading that link now dzervit, thanks

 

I've got the old GTech with the 2 digit LED display...works great and seems quite accurate. Have ahd it for years...is small and easy to "install", all it takes is a suction cup to the windshield, plug it in, and move it up and down until the readout says .00
Then hit the button and hit the gas. 0-60, 1/4 mile and speed, and 60-0 brake distances. Easy.

 

The UPS man dropped off the Gtech this afternoon. I'll play with it tomorrow and post some stock numbers.

 

Here's the numbers I got from the Gtech this morning.

0-60 in 9.43 sec
1/4 in 17.14 at 81.9 mph

Completely stock 2wd Scab, 5.4L, 3.55 LS.

 

Where can I buy one of these?

I want to pay much $$$ for a device it to tell me trucks are big and slow.
