It's hard to read those results, but it looks like you passed everywhere except NOx at 25.

Do not add octane booster.

Whether you put the stock cal in or not, ask the tech to try running the 25 mph test in a higher gear.

You passed (barely) NOx at 15 mph so it's possible, just by running a higher gear for the 25 test you can pass there, too.

Make sure you have clean, fresh gasoline from a station what pumps a lot of major brand fuel. Get the cats are freakin' hot before the guy runs the test. Highway driving in 4th gear or around the block a couple of times in first or second such that the engine runs mid-range rpm.
