......And a quick flash back to the original tune greatly improves your chance of saving your warranty since their equipment can't seem to tell if it's been tuned and set your ECU back to factory settings before you take it in for service. V8 guys aren't so lucky.....
Good idea to go ahead and keep that EZ Flash cable Trifecta sends to you. 200.00 seems a small price to pay to have this option.
