The bug is being boringly reliable! I've fitted a better header and modified the downpipe with a splitter to separate out the wastegate, also an extra muffler to make it a bit quieter. I also fitted a wide band lambda and went on mapping course so may have a bit of a play in the future.
For now I've updated my daily driver to a Tesla P100D which is ridiculously fast!!!
Thinking of a new project with Tesla powertrain now...
