DC Sports Header install and evaluation - Toyota Yaris Forums

I disconnected the battery for a couple of hours today and went for a heavy footed drive up and down highway 280 and then up and down some hills.

At first it seemed like nothing was different. This is probably because I was skeptical the ECU would change anything given I had already driven the car for 100 miles or so.

Well, I was totally wrong. The low end torque feels like it's back! I did some "tests" up some of the steeper hills in my neighborhood and I can definitely feel more power down low. I don't know the exact extent of the change when compared to the stock header but the throttle response really is better and the engine just feels like it has better pull than before the ECU reset. I can say that disconnecting the ECU definitely helped things and anyone adding a header should probably perform the reset. I'm going to go on an early drive up highway 1 to Tamales Bay tomorrow morning, grab some breakfast and see if it gets even better!! Thank you all for the suggestion.
