If your mods significantly disrupt the air:fuel ratio from what the ECU has programmed in order to meet the ULEV emissions criteria, and/or keep the engine safe, it will regulate other parameters to compensate. Whether or not this translates to a loss in power depends on the specifics of the mods and combination of mods.
As to you feeling this change, it is probably more psychological than anything else. A few weeks after driving your modded car, you will get used to the change and will forget what the car felt like without the mods.

i didn't believe it either until a dealer re-set my ecu to get rid of the cel light. i wasn't expecting anything and didn't even think anything of it. but the difference was substantial. i have intake/exhaust. now i reset it once a week. yes it make a difference. read what technosqueare has to say about it on their web site. i only started looking into this question AFTER that incident so i wasn't imagining it.
Every week , that would get old fast. Does a full ts flash help if you have little to no mods? I know you have the rev raised to 7100 RPM but would it improve a stock engine meaning give it more power?
