Prepare for an ear full by everyone

Ill touch on the main points, the VGT, you need it. With it gone you have two options, custom tuning that can make it work but will 100% take a huge amount of life out of the engine. Second is put it back on.

The engine is designed around it, sure it runs fine at speed or more accurately seems okay. The issues and stress and utter loss of control within that engine right now is biblical. The idiots selling the VGT DEL idea will advertise better power and economy but cant tell you why, I've touch on this along with others in another post. The benefits are a direct result of the programing needed to make it functional, and those changes are causing irreparable damage in your engine. Given your symptoms you may be in a balance of your engine not able to work with a critical component missing and extremely harmful tuning.

I would recommend going back to a VGT or start saving money, cause it will cost you an engine again.
