Hi Dan,
I havent actually seen or used a G-Tech meter but i do have a vericom
VC200 which is an older version of the same thing. The VC200 works well
but you do need a fairly level flat area for testing. I used an old
airport runway and got HP and quarter mile time's within the same
limit's as you quoted. We tried it around corners on a race track and
found it hard when carrying a passenger to read the meter to consistent
G forces.
