Don't think they are but I must agree it would probably work better on an FI car a you're moving quite a bit more air.
RCTS is probably the best tuning shop in town and I would not hesitate one second to go through them if I had the cash.
They are expensive and are probably overquoting you to be on the safe side but I would say 5-600 is probably where you will be by the end of it.
Once it's done you will have something that is safe and optimized specially for your car at this altitude.
What time on the 7th? If it's after 5pm let me know and I will be there for "support"
btw not to thread jack but I have a new toy too!
