1988 928S4 running rich

why does it have 944 injectors? what size are they?

I would suggest you have someone very knowledgable go over the entire fuel system including fuel pressure, dampers, regulators, MAF and injectors

The 928 has 2 computers, the LH handles the fuel injection that can be programmed using a Sharktuner and the install of a special eprom but you have to get all the maintenance items looked at beforehand.

Hi all! I will get some pictures and get more information to you but it may be a couple of days as I work out of town. Thanks and thanks in advance to you all! Totally new experience for me!

Yes I would make sure you get some Sharktuning done. What do the plugs look like?

Supercharger kits. Trouble-

Yes, sometimes in more ways than one:D. Seriously though, if they are done right and kept modest they are great for the 928. Obviously the more boost you go the less built in factory safety margin you have. Everything is a balancing act.
