power increase, BHP 210 and +80 torque. Hoping for around 10% better MPG
how can you get more power for using less energy ?

We are putting our MoHo to http://www.quantumtuning.co.uk/ for tuning.

Less down changing means better fuel economy. Simple really.how can you get more power for using less energy ?
As you said, they are franchises but we checked and our local guy has a pretty good reputation so I’m hoping there’s not horror stories.I had a nightmare few weeks with Quantum tuning. Asked them a lot of questions first which they were unable to answer, although they made a variety of false promises. After claiming they had done several remaps of my vehicle (2003 Mercedes 2.7) they finally admitted they hadn't, and didn't have the round OBD port connector that it uses. Turns out it is just a franchise with basic training for a monkey to connect a laptop via the OBD port and press a button to upload a generic diesel map (they claimed to have custom maps but this was false - at best they had something tat worked for cars fitted with that engine).
After some major arguments their head office contacted me to resolve the problems and asked me to send off the complete ECU so they could write a custom map directly to the chip (more specific to an automatic 6 ton motorhome than the higher revving ML series passenger cars). Turns out they couldn't do that either, even in their head office. Nobody had the skill or knowledge to reprogram it !
Eventually had it done by Mike at https://www.mpgtuning.co.uk/ - who was infinitely more knowledgeable and professional. Slightly more expensive as he had to replace the factory locked chip with an aftermarket one that was 'open' to programming, and a custom map for my requirements based on the vehicle weight and my usual driving speeds (no point going for the daft figures quoted by others for driving flat out at max speed).
Maybe Quantum aren't so bad with other engines but worth asking them some specific questions about exactly what they plan to do.

Or just improve the efficiency of the engine, and get more power for less fuel...To generate more power, an engine needs to be able to burn more fuel; laws of physics and thermodynamics dictate this..

Diesel engines run at a temperature determined by the cooling system that has to be much more robust than that needed for a petrol engine. Combustion temperatures in a Diesel engine are considerably higher than those of a petrol engine which is why they produce more N0x - hence the need for EGR or Adblue. Remapping will only add more heat if the extra power developed is used by travelling more quickly: most users are remapping to modify the torque curve to improve output at lower engine speeds.Thought I would add my penny's worth
One off the reasons diesels have the ability of mega miles is that they run cooler than petrol engines
One of the down sides of increasing the power is you will increase the heat produced
Going from 130 bhp to 150 on a x250 is unlikely to have much effect as the cooling system is the same.
But as others have posted not all rechips are the same and you could be putting the longevity of your engine at risk as well as the odd clutch
Yes, hope so too. Problem for me was that my MB engine is fitted to a wide range of vehicles. A generic map might suit a car driver or even a Sprinter panel van, driven by a courier who needs to zip through city traffic with not much weight, getting max power from each gear. Different to a permanently fully loaded 6 ton van with different gearing that cruises for long periods at a steady speed.As you said, they are franchises but we checked and our local guy has a pretty good reputation so I’m hoping there’s not horror stories.

Nobody is running on jet fuel. Chipping is very slight changes to the engine "brain". I wouldn't think there is reason to worry about this.Before /at the time , I would be fitting an EGT guage as this is a very important reading with a Turbo diesel vehicle , increased power
requires increased fuel burn , with resultant higher egt , unless other measures are taken to ameliorate . Exceeding egt safe limits can be catastrophic even in fairly short duration .
