I got my car with 106k and a JDM B16a swap with a mugen stage-II ECU (PR3?). Lately it seems very sluggish during acceleration, it’s like the torque I used to feel at higher RPMS isn’t there anymore, and the low rpms are terrible. Compared to how it pulled when I first got it.
There is about 114k on the car right now. I searched and maybe a full tune-up would help :shrug:.
