dont get a piggy back! it might be cheaper but in the long run mg will spot it n warranty will be gone, all that mg normally do is reflash the ecu back to std (they dont notice its been chipped unless they r looking specifically for it) n u just take take it back to where u got it chipped to get the ECU re flashed

Ummmmmm, a piggy back chip plugs into the loom and can be removed whenever you want in 2 minutes flat. This means it is not going to be spotted by MGR as it won't be there when serviced.

A reprogram can't be removed and will invalidate the warranty if seen by the dealer and it can be blamed for the fault. It will show up as soon as they plug it into T4, not just when they are looking for it.

Most places will charge to get it re-programmed if the dealer does clear it with a new base map.
