Just be aware the G-Tech is very optimistic. I have one and use it and have used it on cars that I race. The G-Tech is always about 2-3 tenths too quick in the 1/4 mile compared to the track timers.

Well aware of that. The 1/4 mile times have proven inaccurate, while the 0-60 times have been quite accurate. I only use the G-Tech for 0-60. Thanks for mentioning it, others may not know the G-Tech 1/4 mile times are worthless...........

0-60 is off a little too. Going by my 60' foot times with my old Camaro and Corvette at the track I could tell. Plus if it's off 3 tenths in the 1/4 it will be off 0-60 too. I'd say it's off about a tenth or so depending on roll out.
