I know there aren't alot of self tuners in the mustang world but I'm curious if anyone has monitored their IDC/IPW pre & post fuel system upgrade to see if you had a noticable difference. Reason I ask is that I threw in one of the DW 400 fuel pump kits in my 14 and there was simply 0 different before & after for IDC & IPW. Right now one of the last pieces to my puzzle is getting the fuel system right, with the procharger 47lb injectors I was going to 100% IDC at 6200 rpms and leaned out so I bought ID1050's which bandaided the issue and now when I'm at 7500 rpms I'm at around 75% IDC in the summer heat. This is on 93 pump though so knowing that E85 needs about 30% more fuel 75+30 doesn't sound like a good mixture. Currently I'm only in the 600 wheel range so I'm 100% confident the 1050's should be good to 800+ on E85 with good fuel pressure.
Obviously I was hoping the DW400 pump would get my fuel pressure steady but apparently its not working out as I had hoped so my next step will be a full fuel system but I would be interested in anyone that has before/after data from adding a return style fuel system.
