Yes I don't either use P&G if the push is 7s and glide is around 10s. In this case I see the gain is so little I dont bother to stress my engine and gearbox...
But when I did the glide in higher speeds with little load the push is the same 7 seconds but the glide is around 16-25 seconds depending on the road conditions etc. This is also more relaxing to drive because you dont have to press clutch all the time.
I also think you need a turbo diesel to do this more efficiently?
This weekend I also cleaned up my intercooler which was pretty clogged. My IAT temperatures were rising in higher speeds so my max speed was 75mph. Now my IAT temperatures are 20 celsius lower than before and dont rise over 50 celsius. So you should clean your cooler now then to get the best gain of it
