i have no way to scan while driving..
got the car tore apart
for LIM gaskets..so i cant go test drive...
OK..i just looked at a crappy video i made and
third gear 60 mph is at 3k exactly

Got the car together, went for a drive. 3rd gear at 62mph is dead on 3k.
4th gear at 70mph is roughly 2200rpm. what do you think, 3.29's or??

I think that's 2.93's personally.

I think Bill is right because in my 00 GT in OD I cruise right around 2200 at ~70mph. This is of course with the 3.29 gears of the GT. Being you have the GTP I don't see why it would cruise any higher at 70mph than a GT even with the 2.93's. I would think they would be just about the same, but never rode in a GTP to see the difference.

An Sc'd car with 2.93's and our slight tac differences.. it's about right for 2.93's. 3.29's would put you closer to 2400.
