FWIW - I check for TSBs daily on all MY S197s. I try to post them in the TSB sticky in the appropriate sections

...I tried the link on several different PCs - worked everytime. Is anyone else having a problem with the link?

Thanks for posting the TSB. I kept having to log in and then nothing...Funny thing, well not funny at all, is that I posted the no TSB 5 minutes if that after I spoke with the best tech at my dealership...go figure. So I stand corrected too.

I'm calling back tomorrow...

Can anyone tell me how in a 2011 auto GT each gear top speed would be affected if my tune shifts at 7K opposed to 6800?

Is there a formula or way to figure out the difference or is it a test and see type of thing?

I got this from another site so take it for what its worth:

Top speed in 1st gear @6800 rpms:
3.31's = 45mph
3.55's = 42mph
3.73's = 40mph

Top speed in 2nd gear @6800 rpms:
3.31's = 68mph
3.55's = 64mph
3.73's = 61mph

Top speed in 3rd gear @6800 rpms:
3.31's = 98mph
3.55's = 92mph
3.73's = 87mph

Top speed in 4th gear @6800 rpms:
3.31's = 126mph
3.55's = 117mph
3.73's = 112mph

Top speed in 5th gear @6800 rpms:
3.31's = 166mph
3.55's = 155mph
3.73's = 148mph

Mph = td x rpm / gr x 336

If you google top speed calculator, there's a really good website that you can plug it all in to.
