can someone please explain to me how upping point of opening on the injectors helps? i know that that the injectors open when the pump hits them with pressure and all that. but does it change ignition timing, burn quality, or what. also how much of a change makes what kind of effect.

feed me knowledge..

also, at the shop i work at, we have a flush machine from BG products that is rather simple really. it runs the engine on BG's cleaner only (you clamp off fuel lines/ pull fuse or whatsoever) people have given us very good feedback from it, but we also charge 225 for the service (at least 150 of that is labor though) BG makes them for diesels and gassers.
