need a tune!!
Removing the secondaries wont give you any more performance and removing the resonators make the car sound like crap in my opinion and does nothing for performance either.
My car currently has the fastest tune only time with the OE tune. But as with all records they are there to be beat. MHP had it before me.
Eurocharged has the V3 now. I haven't seen any track data from it though. Only Dyno. Dyno doesn't really tell the whole story.
MHP or OE tuning if I were you.

Regarding the tune, I just got the Eurocharged V3 tune and I'm loving it...haven't had ample track time to really run plus i'm running street rubber but the power increase is SUBSTANTIALLY greater than stock. Also did K&N and CD.

Nothing deceiving about it.

Yes the C63 with drags on it in cool dry weather really moves. A must to experience your car at least once on the track.
Other than that you cant do anything without the tune. How could tune only be the worst modification? You need to tune to do anything else. Unless you mean esthetic mods like hoods and trunks.
When I bring my tune only to the MB dealer with a warranty issue and you bring in your headered catless car that is so loud it will wake up half the neighborhood on the way in to the dealer who do you think is going to get turned away? Me or you?

When talking about performance mods the more you mod the bigger chance you have of being denied a warranty claim. Exhaust work and cat deletes almost guarantees a denied claim unless you know the SA. We have seen it on the forum before.
