About 10 years ago, I purchased/obtained three different aftermarket "high performance" chips for my E500 in an attempt to evaluate their performance.
None of them amounted to squat in terms of any sort of improved performance.
Here are the instructions that came with one of those chips. I happened to come across the instructions when I was cleaning out my garage shop over the past couple of weeks.
Perhaps one of the Chip Performance TuningCaptain Ahabs aficionados on the forum can utilise these instructions in search of their performance Holy Grail.

Cheers,
