Recall # WQC39 - ECM Reprogramming for Coolant Thermostat

^^Reduced performance can't be the intended fix, can it? (Serious question.)

Parked the car and drove to work this morning (only 3 mile commute), so probably have less than 25 miles on the car since reflash.

Sort of feels like those Mercedes Benz throttle, requiring lot of throttle tip in to get it to start moving, except now it's throwing off my manual transmission timing. Have not stalled it, but got close to it from not giving enough pedal tip in compared to before.

Hope it goes away or my right foot adjusts to it.

Don't sweat it ... all will return to normal. Take it out for a longer drive with some highway driving and response will return faster.

I got it done a while ago and never noticed any difference from before to after. Would an Automatic Transmission respond differently? Maybe someone has an answer.

I don't feel a reduction in performance, just requires more tip in to get the car moving. Once moving, it drives fine. In fact, the torque dip felt less noticeable when I drove a bit tonight, but I will have to try some more WOT chances to be sure it's not just in my mind.:happy0180:

Got my ECM reflashed today and now the car feels shitty and underpowered

I just got mine done on Saturday. It did feel crappy at first but your ECM has to get used to your driving again. Give it like 20 miles of your normal driving style and it'll be back to how it was in no time.

Give it some more time. Please let us know if it improves...
