Tune Required

So I just bought a user's C63 equipped with the following performance mods:

MBH Long Tube Headers
MBH Mid Pipes
ROW Air Boxes with BMC Filters
Weistec Oil Separator
Weistec Head Studs with Gasket Set
Weistec CNC Ported Heads
Custom ECU Tune

my next move was to get MBH X-pipe. By installing the X-pipe will I need to get it retuned to get the best out of the car or is it going to be negligible in terms of efficiency and power output? Also what other mods out there are able to get a few more HP out of the car?

I'm pretty sure the gains would be minimal with a retune. As far as other mods, there aren't too many. You could do cams but people don't see too many gains with those and they shift the powerband higher up in the rev range. Maybe start to lighten up a lot of the rotational mass: wheels, brake disks, driveshaft, etc. You have pretty much as much as you can do while remaining NA.

No need to retune for x-pipe. Im surprised with those $$$ mods the xpipe wasn't done already, usually sec cats and/or res delete is typically one of first mods people do. All the basic naturally aspirated mods are already done. Anything else would not be worth the money in terms of gains i.e under drive pulley, cams, throttle bodies in NA form.. Next step for power is either a supercharger or nitrous. or weight savings.

Get the X-Pipe, don't worry about the tune.

If you have deep pockets, contact Eurocharged about their new M156 Rear Mounted Turbo setup

Or, go for the Magnuson S/C, or Weistec.

Magnuson offers more power than the Weistec for lower cost.

You don't need a retune. You're also basically modded as far / well as you can be without doing a supercharger.

As chris said, look to lose some weight.
