Very qualified guys with lots of experience. Recommended++. Go talk to Sim & Miguel, very nice guys.
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.
