Default 331 to 373 Gears
I currently have stock 331s in my GT with CAI and SCT performance tune. I redline at 70mph in second and 100mph in third. What will be the redline speeds in second and third with 373s?

exact numbers would be more accurate.

What 2007 are you in with only 4 gears?

Assuming you mean the automatic (which has 5 gears) and your redline is at 6,250 with a 295/30-20 tire:

1st: ~40
2nd: ~53
3rd: ~83
4th: ~129
5th: ~172

Someone correct me if I am wrong
