I used to own a 2005 Tip S4.
I now own a 2005 6mt.

The MT car will take the Tip car all day long, unless the driver stalls the 6mt.

With a Tip and the DBW issues of this car, it's the most inconsistent car I've ever driven.
(Pcars, Ferrari's, Aston's, etc....)

Stock 0-60 numbers for 6mt, with Gtech Pro and GTimers range from 5.1+ as said.
I've done alot of tests with both cars and both timers, as I own both timers and have owned both cars.
Tip numbers were anywhere from 5.3-5.9 and varied sooo much it was rediculous.
(tests done with 2 different Tips and 2 different 6mts for comparo)

Matt Stone, the driver for MT who did a 4.99 in a stock 6mt S4 is an amazing driver.
I HIGHLY doubt any 'average joe' could get that out of thier stock 6mt.
The Tip wouldn't come close to it.

I have NOT done any dyno's or timed run with my car yet, as I have one more 'custom' thing to do to her.

I'm betting it's in the upper 4's though.
We'll see in a few weeks.
