1) ground the altenator straight to the battery applying jumper cables to bypass any probable lousy grounds
Effectively it defenitly would not sound rights, that is obviously! And throttle respons with ITB's ought to be crisp and swift.
I'm not super accustomed to the ITBs, so I can not don't forget from the setups I have witnessed if Every single throttle provides a vacuum reference line or a thing very similar? If All those are not linked you could have some good vacuum leaks.
