I have had a Vericom for many years and found it to be a great tuning tool. I bought the G-Tech because it is a lot smaller and I can download the data from each 'run' to my PC to compare it with other runs. It also captures rpm so it will give you rpm vs HP curves to allow you to optimize shift points.
You do need to get it mounted well to get accurate and consistent numbers. I have checked mine against the 1/4 mile timers at the local drag strip and it is normally within about 0.1 seconds and 1 mph. The times it wasn't so close I found that it had moved a little during the run. If there is a bad thing about any of these 'meters' it's the suction cup mounting that they use. You also need to set the 'roll out' on the G-Tech to be consistent with the way you stage the car at the track, and make sure you stage consistently run to run. Of course this is only if you are trying to correlate to the track timers and doesn't matter if you are just using it for comparative tuning.
The HP and Torque numbers are significantly different to those I obtained from a chassis dyno but again seem to be consistent from run to run. It is a good tuning tool and will help you get the most out of your cars engine, chassis and help you refine your driving technique. I wouldn't rely on it to give you accurate (absolute) HP and torque numbers.
I have found the G-Tech to be a very useful tool allowing me to tune the suspension to get the highest G numbers in both acceleration and also cornering. Sometimes what feels quicker by the seat of the pants isn't. Any of these meters will give you very objective data to make adjustments to your car and driving technique.
