Thanks
Thanks
I have forgotten the directions that the errors take, but I recall that ets are a bit pessimistic and mph are a bit optimistic.

I don't really like my g-tech. Haven't used it since about 2 weeks after I bought it (about 8 months ago). I guess it's not too bad to gauge performance increases, but you have to have a somewhat accurate vehicle weight and a REALLY flat, straight road to run on. But the only way to really know if a mod made a difference is to go to the dyno or the track.
I see no point in wasting the money for this thing that plugs into your cars power somehow showing ACTUAL REAL gains and or track times. I just don't like the whole idea, plus its not what that thing tells you that your car can run. Its what you as a driver can make the car run; so make that biatch run!! just my opinion
Like its been stated, the HP numbers, track times and speeds will not be deadly accurate. I did however have great sucess using my gtech (in HP mode) to tune my car in conjunction with HP tuners. It will definately tell you how each change affects your motor. With stock 3.42s i ran up to the top of second. With my 4.10s i run up to the top of third. Take it easy in the first (and second) gear and hammer it in your desired gear. As long as youve got it calibrated correctly and the road is flat, youll have fairly accurate and repeatable data to compare against after each mod.
