Remap or chip (tuning box) - Gazza
Hello all,

I have been running my used 2003 S320 CDI (204 bhp) for about 10,000 miles and it has been brought back up to excellent condition mechanically through a full service, some new injectors, propshaft couplings etc.

Now I am looking for something extra from the 320 CDI which I believe tuning is widely available on this engine.

What I am looking for is the following,
- no more torque between 1,000 to 2,000rpm;
- possibly 15% extra between 2,000 and 4,000rpm; and
- extend the torque and power to 4,600rpm redline.

At the moment, there is a feeling of the torque reducing dramatically around 4,000 to 4,200 rpm which is when the auto box changes up.

What would be the best method to achieve this - Remap or tuning box?

Thanks in advance for your replies.

Kind regards,
Garrison
