I assume this is a 2.4? Could be tuning, HP tuners, and who is the tuner? Also did you use the same dyno? What did the torque number look like? Maybe you lost a little whp and gained some torque or changed your powerband.

You can certainly dyno less hp and tq but if it’s in different areas for a longer duration, it can make the car faster. You say it seems more powerful. Have you done any test runs to confirm it’s faster? I could see lower peak torque with lighter components. Also different times of the year, temperature can cause variations of dyno numbers. Don’t know if that has anything to do with it. Do you have the previous and current dyno numbers to compare? Seeing that could help decipher the difference.

Hell I seen my car dyno 300whp 365tq twice in a row, in October 2018, then in October 2019 ont he same dyno my car dyno's 280whp with a slightly better turbo, twice. I talked to the shop they pulled my car off put it back on reset the wheel base, and on the 3rd dyno pull it dyno just abotu 340whp and 355tq. Even the same dyno the the same day can give you different numbers.
