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.

Thanks

What kind of numbers did it put down, and the Dinan doesnt put down that much power alone with out supporting mods. I dont think with just a Dinan your going to get much wheel spin.

What type of Dyno are you using? keep in mind that without proper air being pushed into the intake you will never be able to get real power generated.

What do you mean by saying wheel spin? Which gear? From a dig or roll?

I don't know about AT, but I had wheel spin in second gear even when my car (MT) was stock. And my rear tyres are 275/30 R19.

wheel spin shouldn't be a factor. You are getting too worked up over the dyno numbers honestly. Each dyno will be different. If you wanted big numbers than you should have gone a different route. As long as your car fells good when you drive it than don't get so worked up in this. Your dyno will make a huge difference since Mustang dynos, dynodynamics dynos and dynojets all do things differently and give quite different results.

That's the reason for the thread. I'm not hung up on the numbers themselves, only how much power my car is making (although the mustang before me laid down 612 at the wheels compared to my 276).
I've tried every scenario, traction on, dtc pressed once, dtc completely off, auto, ds mode, m1.
A friend who had an older Vishnu in his 07 had no problems lighting them up (we can't compare cars because he already upgraded to a M3).
I'm not looking to spin the tires (i have a 420hp mustang for that), I only want to know how the Dinan is supposed to perform. It pulls hard when it's going, but overall not as much as I expected, especially off the line.

Again, I'm only asking about cars with step

Thanks

Dinan doesnt make there products with big power in mind. Get a jb+ and leave it on Default/lower setting... prob fixed.
