Word of warning especially if you are tuning...ALWAYS tell your SA to inform you BEFORE they upgrade your ECU! If they ask why, tell them the truth! You dont want the dreaded turbo lag with 29.2+. Also, if you have AA Xede you will need to install it differently by leaving off (if i remember correctly) 1 of the intercepted wires. Go to their website and download the .pdf and look on page 13 (or maybe page 16...my memory is going bad due to the high speeds I now drive).

Also, if I were you, I wouldnt just 'turn off our tune' with the valet switch. The minute they open your hood (even for an oil change) and see the black ground wire coming from your ECU you can pretty much assume that your car will be flagged for a voided warranty. Better be safe than sorry and take the 20 mins to remove it from your ECU!
