Universal dyno - wheel spin

I'm still trying to get to the bottom of my tune. Got a Dinan Stg 2 flash in my '08 w/step. There is some improvement, but nothing down low. Had it dyno'd, numbers were low, took it back to dealer, they checked for fault codes....nothing, so here I am. Before I resign to the fact that this is all I get, I want to solve one final question.
My car is a stock e90 sedan w/sport package(stock potenza's). I have zero slippage regardless of which traction or transmission mode I'm in (when accelerating in a straight line).
Should I have any wheel spin?

Not that I really want wheel spin, I just want maximum power from my tune. Looking for comments from other sedan owners with auto and Dinan S2.
