i have heard alot of people slam the gtech's well last night i got to do 3 runs with the gtech at the strip to check the acuracy.

first run .06 off
second run .01 off
third run .05 off

seems prety acurate to me, less than 1/10 each run, not too bad, i think i will keep using it.

 

The gtech et CAN be accurate if you use it right. Usually MPH is way off. Was your MPH off?

 

i only looked at the first run mph and it was 2mph off, i have heard it is way off for the mph.
