just bought g-tech pro competition the other day. thought people would be wondering about it and how nice it is, if you dont know its a console that plugs into the cigarette lighter, and reads out 1/4 mi times, ect ect, and supposedly meastures hp/trq. Just thought id give my testimonial, its pretty cool, even if it doenst measure times/hp right, it still is a sweet aftermarket tach with a shift light

Yeah those things are pretty nifty and can be very very accurate as long as conditions of the trials are right.
