I have a late 99RS, and just did the Final Drive last night. (That stupid cup is a little bitch.)

I'm wondering why it doesn't seem to help much. I know the turbo lag makes it hard to feel the gears, but the only time I can even remotely feel it is at the very top of 1st gear around 15-20mph.

I know I got the right gears cause I went back and checked the part numbers, and my speedo is noticeably off.

Somewhere I saw unfounded rumors that some 99's don't respond to the FDmod as well?

Ah well, the butt dyno is always wrong... I'll datalog at the track again next Thursday and post results for sure.
