ECT Power - car jerks when braking
 

So, I've been driving my car in ECT Power mode (I usually drive in ECT Normal mode) for the past few days to see if it makes any difference in MPG. I notice that the car jerks when braking on the freeway (note: this is REGULAR braking, not slamming on the brakes because everyone in L.A. is doing it).

I also notice the following "symptoms" :

Car has a tendency to pull forward when stepping on the gas like a turbo is kicking in.
Car revs higher.
Car jerks quite a bit more often.

I have only been driving for a few days, so I don't know if it makes any difference in MPG yet. Will update once I have that info.

Anyone else notice these symptoms? Any info is greatly appreciated. Thanks!
