So as the title states, my final issue followed this path:
1. Installed Aeromotive AFPR: Car starts, no issues.
2. Installed Wally 400LPH: Stock wiring still, car starts, turn down the base pressure a bit, no issues.
2. Installed FIC BM1650's: Getting the car going was rough. Took a bit to figure out the deadtimes. I could get it running but was having issues at WOT. If I changed some of the sliders to weird values I could get the WOT pretty decent but then if it stalled or I stopped I couldn't get it started again till I set the sliders where they needed to be (at the cost of WOT again). So I researched and read that the alternators are kind of shit...
3. Installed Saturn Alternator: Used a relocation kit which wasn't half bad. The brackets had to be modified and one of the belts needed to be replaced with a shorter one as the one supplied caused the alternator to hit the subframe under load. Also needed about 4 washers to shim the kit for the power steering pump part...so i guess it was kind of a crappy kit haha. Meh...moving the alternator made a shit ton of room up front so all in all im happy. The saturn alternator packed a punch too, got a solid 14.4V right at idle and at all the low potential spots from before. Had to reset the deadtimes again to get it running but it seemed to help a lot overall. WOT and idle were both decent, but now I had a studder at about 2.2K and could not get over 4.5K at all. More research lead to the 1650's being weird about deadtimes and draw and voltage and other drains in the system...
4. Installed FIC Easytune box: Immediate difference, set all the deadtimes the same and it fired right up. Multimeter shows 16V at the injector resistor right at idle...huge jump! Still could not get over 4.5-5K... now the logs showed that the injectors were getting decent duty but the WB showed lean ass hell. More research turns up the stocker pump needs a rewire as theres huge voltage drop in the stock wiring....
5. Fuel pump rewire: Straight forward, car starts but really rough. Check the fuel pressure and it shows 60+ psi. I think sweet, lots of voltage and flow now, so i back the screw out until its at 0 and it still shows 58 psi. I cannot turn it down enough now...reverse problem....too much fuel! I check the voltage at the pump and it shows 14.4V...so about 2.3V gain but right where you want it to be. I research more and figure that it could be the stock fuel lines restricting flow...
6. Installed tank to rail return/supply -6AN: Installed was a bit challenging....those lines were way beefier than the stockers. Does not help the issue. Still waaaay to much pressure. So I took the AFPR apart to check for a blockage....nothing. So i figure it must be the gauge, installed a new one....no dice. Same high ass 58psi. So i was thinking maybe the little orifice in the AFPR was too small (reaching for straws here I know) but I drill it out an extra .22mm and reinstall with the same preset. I figured if that was the issue then there should be at least a small change in the pressure. Nothing....
So thats where I am at. WB shows Lean but I believe that to be rich knocking causing puffs of missed unburnt cylinder air causing high O2 readings. Tons of pump (pressure and flow), injectors to flow them, and an AFPR that appears to be sized right. I am not gonna upload logs cause they're useless....the DSMLink thinks everything is running fine except for the WB...
I am totally out of ideas now....anyone have some fresh ones out there?
Second set of "eyes" needed....
