seb de la run

in reunion island they re few c 63. so no many tuners can flash it.

but i already flash my car :

audi s3 / 147 gta / 535d etc...but now i have lot of torque than a bi turbo diesel like 535d!! and more power in 5500 trs...is very pleasure.

i see you modiefied your c 63...what do you about pulley? what is your advice for the next tune?

pulley? carbon intake?

i dont like headers and exhauste because like the original v8 sound.

i heard akrapovic titanium on c 63...i dont like and mainly for the price.

The pulley and carbon air intake will not make much of a difference and they are pricey too.
After you got the tune it gets more expensive to make the C63 faster.

Headers and a matching tune is the next step you should take if you want more power but the car will be much louder.

Like Matt said, once you have a tune if you want more HP there is not a lot of options: headers or supercharger for real HP gains.
Now you still can put a full exhaust for 10+ gain and sound, change your filters etc.... CF air intake is more for look than performance IMO.
Since your car was imported from Italy I'm curious to know if you have the ROW airboxes from factory?
