Calibrating for the exact vehicle weight I hear is very very imporant for them to be accurate.

they can be inaccurate,back when i had a 02 v6 mustang,me,my brother and our friend went out and ran our cars.my 02 v6,i ran 16.7,not bad for a v6,then my brother in his 98 gt,16.1,not good,then our friends in his 89 5.0 lx,he ran a 16.4,something had to be wrong.i knew that me and the 89 would be close but the 98 gt should have down alot better.i don't always trust those g-techs.
no all those are slow

take it to a real track i dont trust them anyways, i got a 15.9 off my 02 vert even tho that seems acurate[8D]

What was your MPH?

I had a G-Tech and used it mostly for 0-60 times but for the most part it worked pretty well!!

i would say with 100% confidence that the G-tech is at fault.

I thought the same thing when my stock 07 was doing 6´s from 0 to 60 mph, i mean thats a sixer time. i´m 99% sure he tried that run in a street with some sorta uphill. Even a slight hill kills your time, i've tried it several times

Yes 245/35ZR20

ORIGINAL: Lees07GT

Okay, the width is 245. What is the profile? As in 245/35?
The original tire diameter is 27.2 if your new diameter is the same you won't have any problems.

Ok here is how you get it:

width*profile*2 / 2540 + wheel size = tire diameter

235*50*2 / 2540 + 18 = 27.2

245*35*2 / 2540 + 20 = 26.75

It's about the same so no worries. If your tire width is 265 you'll be right at 27.3
