Yeh, this is a common problem with Skylines and boss kits. Ur boss kit doesnt have HICAS, so the computer shuts it down, which is why it is so hard to turn. You can modify your new one with the old sensors, but its easier to buy a new one. I bought mine from a shop called MALZ, but I think Super Cheap sells it? If not, other shops should have them. The boss kits are made by HTB or something like that. Not sure exactly, but its close enough. Good luck!
