58mm TB problems

has anybody had any problems with a BBK 58 TB? i assumed it was plug and play? is there any kind of tuning for it?
i tried a friends 58 and my tranny went crazy (A4)

If you add a TB to an A4 you have to program for it.

Yeah, you need a good tune after a bigger TB. Just another reason why you don't need a bigger TB on a LT1...

i assume it has something to do with the TPS sensor. i would think i could gain 5-10rwhp with a bigger TB?
