Thanks for above. I was initially going to go had appointment but then backed out. See as you mention warranty affect being major issue and this car is leased. So as a lease I do not own it...BMW does and if forbid anything bad happens with this ecu tune then I am at fault. The ecu tune guys have done quite a bit of work with many setups and their equipment and expertise are second to none. But...I can't risk if soemthing were to happen the liability . Also as you say there are many questions ....they said would redo any flash or set back to originally but at 110 + TX. ... So at end of day I say to myself...extra pickup and go would be cool to have but this car in mainly city driving has quite a bit already...better not to mess with the setup. If I want more power well...wait till lease is up and go m235 or M2. ..or get dinan tune with a warranty. For now I am leaving as is.
