Thanks for the info Mike. Follow-up question: What happens when the dealership service dept "re-flashes" your car? Is your ECU tune essentially wiped out then and have to be re-done?

Also - I think I read on one of these posts that if the redline is raised, the dealership will discover that as it will send a "red flag" when they run their diagnostics. Is this true? I think a lot of guys are choosing to not to raise their limiter for this reason. Can you comment on this? Do we have the choice with your software tune?
