It is definitely not advisable to buy (used) tunes. But there are some good ones being sold on this forum sometimes.

The problem with Jb4 piggybacks especially N54/N55 is that they get modified to suit the purposes of the owner...such as adding or splicing for the use of meth/NLS/Antilag/speed defeat etc. Some of these Jbs become badly hacked.

Ask the seller to provide detailed pix especially of the plugs and the inside of the board. That will give you some indication of at least the quality.

Just make sure you take the JB4 back to its standard settings. For example if the guy had a back end flash on his, you will need to swop from 4/3 to 4/2 when you install yours.

Also the setup could be totally different on his car for example single turbo. So you need to update to the latest correct firmware for your setup.
