I used one of these today (the aussie version in KMh) and i was pretty impressed with the way it worked. Acurracy within 2%. I think it would be a better of checking what effect mods have done to your car. You can get em from rare spares for about $380...

The heart of the G-TECH/Pro is a precision silicon accelerometer. An accelerometer is a sensor that measures
acceleration, also known as G-Force. G-Force is what's keeping you in your seat as you are reading these words and if it
wasn't for the seat you would be accelerating to the ground at 1G (32 feet per second per second).

G-TECH/Pro measures your speed and distance traveled by integrating acceleration over time. Basically, if you know
how fast you are accelerating for a certain time period you'll know how much your speed has changed after that time
period. So, if you start of from zero speed then you'll know what your speed is after every time period. These time
periods are very small (2.5 milliseconds) and that's how G-TECH/Pro maintains its accuracy.

Distance is measured in the same fashion, if you know how fast you are going for a certain time period you will know
what is the distance traveled during that time period.

G-TECH/Pro also measures delivered Horsepower, sometimes called Rear Wheel Horsepower. This horsepower
includes the loss of power through the drivetrain which is usually 10-15%. The formula for Horsepower is speed times
acceleration times the weight of the vehicle.

Apparently the AP-22 performance meter is better....

i have heard nothing but complaints on this unit. several guys on my other site have tried and tested it out. i have a good following on the caddy area that have tested the toy seen here.

This thing is way better than the gtech pro

you can read the review here: this guy is a mod on my site and is not affiliated with either product and may still be able to get discounts.
