When I got my 7th gen manifold I noticed it was such a tight fit to get it down. Make sure none of the hoses are kinked at all. Not running an oil catch can can deteriorate these hoses and can collapse easily. Why you would see a change in its behaviour is the fluctuation of size of the hose.

Re check the hardware and possibly change those TPS. The BOV should be flowing at idle, do not close them.

The stage 1-1.5-2 bump up kits are all the same. The difference is with 1.5 you have the intercooler already, possibly injectors opposed to going from 1-2 directly.
