Flash tune is what I go with. Your pretty much fully warrantied because you can hide it unless you blow the engine(not likely) and still get decent power gains. I am looking for one before I order an M4 noone has one out yet. |
It's common knowledge that you can't hide a flash tune nor a piggyback for that matter. BMW NA during a PUMA case for serious repair claims under warranty looks at a variety of parameters that will give the tune away, even if you flash the stock file, reset the software clock counter etc. Best way to be as safe a possible is to get a spare ecu, although there are other modules that could also give the tune away, but that's a topic for another time.
