I run a fleet of 5 Citroen Relays and 4 Ford Transits for my business.

Does anybody have any experience of using these DIY plug-in tuning chips/units? At approx £400 a pop are they worth it and am I likely to get any problems further down the line possibly relating to warranty arguments, engine failures, etc...? At normal speeds are there any downsides?

I'm looking at the fuel economy benefits rather than power but it just seems all a bit too good to be true. I understand chipping an engine in search of extra power alone will increase the wear and tear of certain parts but I was told that if the vehicle is driven 'normally' then it is possible the life of parts can actually increase. There's logic to that but is that right?

The plan would be to buy one and see how it goes before committing to buying one for each vehicle. Any help would be much appreciated.

Cheers.
