A Triple Back FIip

Doesn't matter what rider (just need's a lot of speed). Go to the caynon level, go up the hill where the tunnel is and go up every gap until your on the big pillar where it has that old cowboy sign, got to the edge and go right to the ramp, before you fly away hold the shocks. You will for sure get a double back flip, and probably a triple backflip. P.S. Try to land in the crater, it's hard to land in there, but more time to land it.

How To Get Sal The Alien

Enter the Fox Creek freestyle course. Jump over the canyon via the ramp, but aim your jump to the left of the ghost town. After you land, continue going along the side of the buildings. You will soon should see an opening and lots of rocks. On the ground is one rock that looks like a two sided ramp. Go into the rock field about 75 to 100 feet. Floor it, swerving around several rocks and hit the ramp. Make sure you are heading toward the buildings. Hit the ramp and aim your jump so you land on the awning cowering the porch of the back of the building. There will be a small separation, but this will not cause any problems. Cross it and there will be a ramp on the other awning. Jump it and land on the roof with the hole in it. Go past the hole, turn around and you will see another ramp. Jump this one to get to the highest roof. This may take several attempts. After you land on the roof, position yourself so that when you jump the last ramp you land on the rock bridge. Jump down onto the ledge leading into an open mine shaft. Continue to follow this path until you reach Sal's UFO. Continue past the ship into the next room and you will see Sal, along with several companions, in suspended animation. You will get the "Find Out The Truth" trophy and unlock Sal as a playable rider.
