Absolutely.  We build very high hp turbo Porsche engines and always run 
open-loop, for both street and the track. My 1000hp 3.8L Porsche engine runs 
open-loop all time and I use it for daily driving (in Texas) as well as 
high-speed events. My dual widebands on  the MoTec are used only for tuning. 
If it's tuned right  (ie, conservatively,  thoroughly), there are no 
problems.
