Ducato remap

can't offer any advice on the remap process (or specific recommendations) except to say that the figures ypu quote (144 bhp and 380 NM) are just about bang on the latest ducato '150' model figures, ie 'quite sufficient'

You don't get anything for free, not in this life. Any improvements to power will have to be at the cost of fuel consumption, especially if you use that extra power. If you could remap for better power AND better fuel consumption then don't you think Fiat would have done that to improve their sales?

most remaps will give better fuel consumption if you drive the same as no need to floor it to get the power. reliability could be the problem and that is why manufacturers don't supply them at peak performance. Your problem is if it's a manual gearbox, will the clutch take the extra power from the engine.

Fiat have done exactly that, with a range of power outputs from that engine. Manufacturers have to meet a middle ground for their engines, to suit a number of markets, fuel qualities, types of vehicle etc. A good remap can be a very cost efficient improvement.

On this particular one, I'm unsure if the 5 speed gearbox / highish revs at speed will actually be the limiting factor in terms of economy on a run, which is why I was keen to hear from anyone with first hand experience.

My last van, an Autotrail Chieftain, on the old shape Ducato with a 2.8jtd engine was remapped for more torque. Driving normally gave an increase in two mpg. Using all that extra grunt, especially towing a car became a chore as the clutch would constantly slip trying to cope so I ended up driving in my old style using more revs, and a loss of four mpg. Numerous reliability issues also occurred so after nine months I had it put back to standard. 

I think it would be fine in a normal van but a motorhome near the weight limits all the time is not worth the money.

I looked into this, a friend who is a mechanic and M/H advised against as JollyKernow said in his experience most that he remaped for clients came back and reversed back, just passing on my small bit.
