ECU power uprades?

From my understanding the extent of any tune of the Zs ecu will simply adjust your air/fuel ratio (maybe timing?). If your car is completely stock I imagine you will see little to no gains whatsoever. The ride may feel slightly smoother.

The general consensus is dont even think about a tune until you have done some of the main air flow modifications (ex. cat back, hi flow cats/test pipe, headers, intake) because this will obviously result in better air flow for the car and thus will throw off the a/f ratio, which a tune can correct.

The only other cool thing you will get out of a tune will be the different maps, which have also been documented in different threads.
