Most diesels from factory have air reserves from highly efficient turbos, programmed into the maps to allow for varied fuels, maintenance and to prevent smoking at any acceleration, chip just uses up that 10-15% reserve

Only the cheap versions do that and it farks the engines real quick. We see it all the time at work.

The proper expensive chips do a lot more than upset the factory settings. That is why they cost a lot more, as they have had the correct programming put in place. These chips are reliable and have decent backup service as well. You get what you pay for. Buying a upgrade chip off someone who is not a specialist is only asking for trouble.
