stock rear gear ratio, '01 Z28

tire size & rear gears...
Now you've got ME confused! I have 245/50ZR- 16's on my 2001 Z28. If the GU2 means I have a 2.73 rear gear ratio, then how did I do 142mph in it? Ah heck... now I'm wondering if I need to reprogram my PowerProgrammer from a 2.73 to a 3.23 rear?
Ugh!!!

If the sticker on the door says GU2, then you have 2.73 gears.

And DS01Z28..............there's nothing wrong with your car! Since you've got Z-rated tires (from the factory) you don't have the low speed limiter, therefore you can do over 115mph, and upto ~163mph if you're brave enough!! Pretty much the only time 2.73's are good is out on the highway for top-speed runs.
