It's an age old debate....
To map or not to map.
Me personally I don't map, and believe the advertised MPG gains are snake oil.... though have to agree that small BHP gains are possible and testable on a dyno.
I'm a firm believe that OEMs build engines for long term use and a long life.... and that running maps and driving hard pushes the engine outside its normal envelope which can lead to excessive wear and tear lead to component failure. Oil bearings in turbos are an obvious weak point from over heated oil, diesel washed oil, old oil, low oil etc etc.
Overheat the turbo and the bearing can run dry . . . . .
For me I think just go for the OEM bigger BHP in the first place... (which i have done for the last two vans).
But I do get the attractions of a map...... but hate the so called tuning boxes that just mess with the boost and rail pressure sensor input to the ECU.
These are obviously my own personal views and opinions and not those of T6F in any way.
