I think you must mean plug-ins like Superchips Bluefin. The benefit is that in the event of an insurance or a warranty claim they can be removed and leave no 'ghosting' in the ECU. Varies from car to car, but I have driven an Audi A4 and a Focus ST that had been Bluefinned and the improvement in torque at low speeds was particularly pronounced in the Audi. This meant it could be upshifted earlier so used less fuel.

I'm considering chipping my Peugeot 3008 2.0 150PS, it's done 62,000 miles. The claimed power increase is 187PS and fuel consumption reduction of 30 per cent. Is this viable and, if so, why don't manufacturers...
My SEAT had the "fix", which has ruined the performance and fuel consumption and will likely lead to EGR failure in the future. Can I reset it by disconnecting the battery? Slim hope, I know.
Should I have the update to my Audi A4 2.0 and, if so, why? I can see no benefit for me and only risk that it causes a future problem that Audi disown. I've refused the update so far.
