Whats this about modified trans needing modified tunes?

I don't understand what you mean about the sentence, "I now feel like my tunes are the limiting factor as opposed to the transmission."

In addition, I don't think that there's EVER been a time that Bill or I have told someone that a valve body change (or a complete aftermarket transmission like a John Wood or BTS) wouldn't need tuning changes. If nothing else, we will caution that the shifts will likely be way too firm afterward. Didn't you have your chip reburned at some point because of that already? I could be wrong.

EDIT:
I was wrong. You had a reburn for the TCC apply issue during the 2-3 upshift.

No changes in tunes since the transmission install. What I meant by that comment is that it was obvious that the transmission was the limiting factor in the equation when it was stock, especially now that I know what a good trans is supposed to feel like. I can tell now that the power is getting to the wheels more efficiently and the trans isn't holding me back. I would like to get some more aggressive tunes, or perhaps even dyno-tuned now that I feel like the transmission is built (and warranted) to handle it.

So, I'm still confused. Do I need to update my tunes simply due to the fact that I added the performance trans? Thanks Cody, it's good to hear from you.
