Guys I'm pretty unfamilier with the bottle on these diesels so bear with me here, so I understand that you want the injection timeing pulled back or retarded as the nitrous is introduced so say in a 12 valve application could the 215 hp pump be "somewhat" of an idea? Or just dump it in and gate the S*** outta it for a 1/4 stretch?! I'm unclear as to how much the 215 pump pulls timeing away (it about 4* or did I dream that up?) and where in the powerband it starts to pull it back or if theres even any way to control it? Im wanting to think no (delivery valves or somethin)? I know its not a computer that your able to manualy tune like a CR but it was a thought I had and wanted to see what yalls thoughts were on it. :Cheer:
