A tuning box isn't a 100% foolproof method of maintaining warranty either, boxes often bring up fault codes
eg:
1 Fault Found:
15343 - Boost Pressure Regulation
P0299 00 [096] - Control Range Not Reached
which may prompt further investigation.............
And - long term trim values (and other anomolies) in the ECU will also give things away. I wouldn't say that tuning boxes are 100% undetectable. Someone who is determined could always find traces ............... Prob not at dealer level, but definitely do-able.

If warranty is a prime consideration with a box, the only "safe" route is to get a MTM box, where they offer a full powertrain warranty.
If it were me I would stay away from generic maps such as superchips and get a custom one made on a rolling road, a decent tuner should be able to remap the car safely.
Rick, what's your opinion on the more advanced offerings - the Abt and MTM boxes?
I've only had to take it off once, just to be on the safe side as I was having a wheel repaired. I would normally but it's such an easy job if you route the wiring properly.I am waiting for a remap but was seriously considering MTM due to the powertrain warranty.
Question for those with MTM: Do you remove it before service work etc?
Once I get my CTS elbow on I'd like to get mine on a dyno and see what figures come out.
An RS3 is on my "goal board" as next car (along with an F-Pace!) and I will be putting my M-Cantronic on it!I have the DTUK box and it has totally transformed the car, and it looks like users of the MTM & JB1 have also mentioned this. It should have come as stock with this sort of performance, but i imagine they needed the extra bhp & torque for the RS3.
The RS3 with one of these boxes fitted must be ridiculous!
