I have a Renault Clio dci with a 1.5L turbodiesel engine. Advertised power is 90HP and 220Nm of torque (162 ft/lb). I have made the assumption that I should accelerate with as little throttle as possible and upshift as early as possible. I usually upshift at about 1800rpm which means I am at around 1200-1300 rpm in the next gear (second gear and up, fourth and fifth have a smaller difference). It is a double overdrive 5 speed manual transmission (4th is at 0.9, 5th is at .67 and the final drive ratio must be 3.55).

Below is a link to a dyno run made by some chip tuner, the blue dotted line is the stock torque curve and the red dotted line the stock power curve. Ignore the solid lines as they are the tuned ones.

Would you accelerate with light or high load? Would you try to keep the engine at 0 boost? At what rpm would you upshift?
