Is my speedo off? or is it g-tech that's incorrect?
 

So I have a g-tech and when I do my 0-60 runs....i'm just above 50mph when it shows my reading on the g-tech. . . .
WTF is wrong???
could my speedo be that much off???

I have 225/55/16 tires on my stock 98SE rims....

I've had readings between 6.81 (my best) & 7.24 (my worst) on the 0-60 runs... that's with groceries, my fiance, & my old y-pipe in the trunk....

Your car is so fast that the needle can't keep up.

















I would say the G-Tech is WRONG.

The speedo is slightly lagging behind. If you ever punch the gas, and watch the speedo, you will see it move a couple more MPH up after you let off the gas. The gear gets a little twisted, and takes a moment to catch back up. G-tech is more reliable than a passenger with a stopwatch.
