Note from Garrett regarding shaft play:
When the Powermax turbo is new, or has not operated for a long period of time allowing most of the oil to drain out, the rotating assembly will move more in the radial direction because there is no oil in the center housing. This condition is normal. As long as the shaft wheel spins freely and the wheels don't contact their respective housings, the assembly will function properly.

My fuel economy went up 2 Mikes per gallon with just turbo then added ppe econo tune and got 2-3 more mpg. The turbo whistle is great as well. I would recommend this turbo to anyone who is looking for the next step in turbos.
