I'm looking for an automatic DD and am stuck between 996TT and 997.1TT. I will be modifying, end goal is around 570-600AWHP, possibly more in far future. As far as I understand, 997TT's tiptronic can handle more power than the 996's. Is that correct? I would love to have PDK in a 997.2 but it seems the PDK is not as strong as tiptronic.

 

I'm not an expert on the subject but what i gathered from my google skills:

1) 997.1 much better Mezger engine but it comes with a slush box transmission

2) 997.2 has an engine not as over built as the Mezger, but it comes with a superior PDK transmission

If your horsepower target is 570-600, you'll be fine with either vehicle.
