they arn't the best for giving numbers to boast, but decent for comparing the same car before and after mods

they are an accelerometer, and according to weight of the vehicle (inputted by the user) they determine the calculated horspower to create such acceleration force.

i love mine, i got it off of ebay, its the g-tech pro. tested alot of car with it, mostly stock ones and the reading is comparable to the advertised hp of the car with the power loss of about 20% to the wheels. the 0-60 is a great feature, and if you have a passenger looking at both the g-tech and the speedo, it stops right at 60mph and gives u the time. i like it! and i would suggest it, but only if u have a place to use it.

The G-Techs are accurate, body roll affects the readings however.

the g-tech pro has 3 accelerometers (X, Y, Z(, so it doesnt have the shortcommings of the old model where not settimg the meter 100 % level would give false readings.

it is actually prety accurate, and a great tool for meassuring differenced in tirepressure, shoch settings, timing and jetting on preformance,

invaluable for adjusting EFI on public roads, just be sure that there are no cops arround when you test 1/4 mile...

and make sure there is enough room to stop. i had an area where i tested a bunch of car for 1/4mile, but they were all slow cars and could easily stop before the road ended. when i tested the first fast car in the same area, it got quite scary at the end of the road, but we did stop.
