The guide's suggestion to use Series 2 "The Gap" was an easy way to pop this one for me. Just a little note, that I think you need to score 10,000 on each landing for it to count as perfect as I landed with 9,653 once and checked my percentage complete for this achieve and it did not count that lower scored landing. (You will see this score shown above your car immediately after the landing.) In order to get 10,000 you have to press X closer to when the inner circle meets the outer circle during the jump that shows the X circle growing inside a circle above the jump visual. Also a little hint is that I think it helps to use boost into the jump to make this jump successfully (although I just tried without boost and it was successful). You start with about 40% boost on your first lap, but then on subsequent laps you can gain more boost by pressing X toward the end of the shiny blue-colored loops and twists.
