Been trying to figure out what gears I have. The glovebox says GU2 but when i used the rear gear calculator on here I got 3.23, it will hold 1500 rpms at 45 in overdrive (a4) and from WOT it will shred tires all the way thru 1st and halfway thru second before it hooks (with the mods in Sig) I am the third owner of the car and it has 170,000 miles so i wonder if the first owner swapped the rear out

Gu2 is shitty 2.73s. Your not ripping threw 1st&2nd with these..

your car might have been changed to 3:23 but GU2 is 2:73

3:23 is GU5

That's the thing about owning an older car that many people have owned. You usually don't know what changes have been made to it, if they're not plainly visible like a rear end change would be.
