One of the common approaches to the potential fix is to say "I will just get a tune to undo the fix". In researching my next car, I've been researching into rules around modifications/tuning to vehicles in Canada (specifically Ontario), and there are a LOT of insurance company-specific issues. If the vehicle is modified in any way from factory specs, e.g. CAI, aftermarket turbo, exhaust, and the changes are not disclosed to the insurance company, your coverage can be dropped.
The guidelines are different from company to company, but still a concern. Now, detecting an ECU update, i.e. a Malone tune, would be very difficult but probably could be done if the insurance company wanted to badly enough. This potential issue would make it even less likely for a fix to be acceptable.
Maybe someone with a tune could jump in regarding the insurance coverage aspect?
