Tis true, the NIStune is a good option I agree. Just food for thought.
How much would you charge to do the Adaptronic? I was quoted $650-$750 to install/tune my Link plug in. Also have to factor in IAT sensor. So if the Adaptronic is similar, then you're looking at what, $1800 installed, tuned, everything? If the NIStune is $1350 tuned, and the OP decided he wanted more power and needed to get the Z32 AFM as well, that makes it between $1600-$1800? Depending on the price of the Z32 as well as installation, etc.
And that's only if he decides to get the Z32 done at the same time as everything else, if he changed his mind later and needed to get it done then that adds another $400 or so for a retune? Whatever way you spin it, the NIStune is probably going to be the cheaper option. But if it's only ~$200 cheaper...
