TDCi 115
Before fitting the plate, my car used to smoke on acceleration and the engine was shaky at 1250rpm and around 2200rpm.
So after fitting I took it for a test drive and the results are:
1 It is still shaking at 1250rpm but not so much at 2200rpm (when driving at 70mph).
2 At first it was still smoking when accelerating but after a little while the smoking seems to have stopped, even when I floor it I cant see any smoke behind me, but it is windy so maybe the smoke is being blown away before I see it...
3 The power delivery seems to have evened out, I mean it doesn't have the sudden explosion of power before 2000rpm, it feels more gradual. It also feels more responsive at lower rpm and a bit more torquey between 2000-3000rpm.
Although when I had joined the dual carriage way, I put my foot down in gear 2, the car was hesitating from 2-3000rpm (and I s***ing my pants) but after that it was fine.
As for fuel economy, I will have to do a test for that. I usually test it by seeing how many miles from quarter tank it goes til the reserve light comes on. My record is 87 so far.
