Avo tuning had this very nice Mercedes 400SL in today for a power upgrade these cars in stock form have 333hp, after a Quantum performance upgrade this will now be a touch over 400hp.
Applying this upgrade has transformed this car on the road with a very linear power delivery.

These cars require the Ecu to be removed and carefully opened, as you have to remove the PCB circuit board from the alloy base of the Ecu which is quite a tricky job, but never the less we are experts here at AVO tuning undertaking some of the most challenging vehicles.
