Hi

2 questions,I have a 2005 Mercedes SL350with 80,000 on the clock with FSH

1. When or what mileage do you undertake a gearbox flush and filter change ?
2. Will the engine take a remap. adding on 30 BHP, is it work doing .

Any help would be welcome

Regards

1. If it's a 5 speed every 40k miles for a fluid and filter change.

2. I personally wouldn't bother but others swear by it.
