Anyone ever try a device like G TECH PRO? for 1/4 1/8 HP Torq ect?
 

I hope it's not another scam. for 300.00

bumppppppp

I've got the older version of it and it definitely isn't a scam. It isn't as accurate as what you'd get at a track, but from what I remember of people who did 1/4's with a G-Tech and compared it to a timeslip using the G-Tech on the same pass it was pretty close.

sweet I just picked one up for 300.00
