    I recently reverted my 2018 si back to stock from 19.5/21.5 map and when I’m almost half throttle it feels like my car is jerking. Is that the clutch or?

    Ok..dont know but dont think its the clutch. If it happens when you dont use the clutch and just cruising. If its just jerking when your shift gears that can be clutch..

    It could still be the clutch... when you shift gears you are actually disengaging the clutch. You may be misunderstading pressing the clutch petal with the actual clutch.

    As far as the actual condition from the OP, if the clutch didnt slip with the more powerful tune, I would not think it would start to slip if reverted to stock power. My question is do you have other mods that would make the car operate poorly while on the stock tune?
