Quoted from d0n:Funny you mention that... the TZ I bought recently played really slow and "floaty". I raised the back levelers as high as possible and lowered the fronts as low as possible. This still didn't make the game play right. I ended up removing the front levelers so the legs sit directly on the floor. That pretty much did it but I'd still like the playfield angle to be a bit steeper.
Also, you can check to see if you have 3" leg levers. PBL sells them for less than $1 each: http://www.pinballlife.com/index.php?p=product&id=921
