with all the stock variables, stock tire sizes and pcm setup, what would 3.73s / 4.10s top out at in a 4l60E?Stock stall Then toss in a 3k stall and then what happens, just tryin to see what the differnce is here!

 

I am not sure what you are asking? If there is no speed limiter set in the PCM, your top speed will be limited by the rev limit and the amount of hp you have available. In the case of an A4 with a 26" tire, 6,000rpm would be 178mph in 4th gear with 3.73's and 162mph with 4.10's. Subtract a few mph for converter slip. But you still need the power to go that fast.

so then i could still probably run 125 then if i needed to still

 

In what gear? Yes, in OD. In 3rd, which is 1:1, 6,000rpm is 124mph with no converter slip and a 26" tire.
