Q : I have 1985 Mercedes 380SL (M116 engine). We removed the K-jetronic and installed EFI instead (with Link Atom ECU and ITB). But we lost the vacuum and ended up with stiff brake pedal and (almost) non-functional brakes. I want to buy iBooster Gen2 to adopt it into my car. What other components shall I order together with the iBooster?
