I had to basically start over. The push kit does not have the trick billet throttle body mount and there's a few other things slightly different things like my turbo doesn't take the upgrade parts they send. I've never taken the radiator or throttle bodies off before, while none of it is terribly hard it is time consuming making sure it is right. Your upgrade should go much quicker as your basically just swapping air box for intercooler and a few other minor things. The fuel pump upgrade is time consuming as well, the directions are straight forward and I had little problem with it. I've yet to ride the sled but I'm hoping to go this weekend.
