A friend of mine exported his US-spec E46 M3 SMG to Europe and had a local tuner fit a Karbonius CSL airbox and do the CSL mapping. The car isn't driving right... it runs okay initially, then starts to stutter after it's been running for a while.
I'm pretty sure the EU shop skipped one or more US-specific steps. Since this exact setup is common on US cars, I'd really appreciate hearing from owners who've done it properly. What does a correct, complete setup actually look like on a US-spec M3 SMG? DME, tune, sensors, coding, SMG, the lot. What's the standard recipe over there?
Trying to put together a list of things for the EU shop to check...
Love hearing your input.
