Side note: I wouldn't expect massive gains on a n/a S65 though .. I just got killed by another 335i today. Get at least primary cat delete done first to maximize gains.
Our n/a cars are losing about 10-12% due to Calgary's altitude. Tuning & cat delete will likely bring it close to the capability of a sea-level car - but with better throttle mapping etc.
I second the recommendation of ECU Tune - great people/service. They got my imported from US M3 coded and helped uninstall side window tint to comply.
