To answer your questions...yes you can drive around on an extreme tune. I daily drive on my hottest tune and it does fine, smoke and power come in handy. With EFI you can make your tunes do whatever you want to beter suit your driving habits. Headstuds aren't really a problem unless you start pushing 500-600 hp or over 40-45 pounds of boost. As for the EGR, you can turn the EGR off with EFI but the valve is operated by a spring and can be forced open with great pressure so i would recommend getting a blocker plate. As well as a PCV reroute. Hope this helps!
