Best NE points for SAFC II???

[Tarantula]

I want your guys opinion on what the best NE points for the SAFC II. Right now I have them with the following
800 1600 2400 3200 4000 4600 5000 5400 6000 6400 7000 7400
Mind you that on this SAFCII I can set it every 200rpms for a total of 12 points. I did it this way thinking that more NE points= More flexibility but maybe I have them set wrong.

The throttle points I have them at 35% and 70%. This is another thing that I would like to know as to what would be good. I have read people having 50% 80% and others where I have them. I figured that because my normal cruising throttle position never hits over 35%, than that is where I would like it. Over 35% I'm trying to build boost.

I'm having a terrible time trying to tune my car. I can't seem to get my car's timing a steady rising no matter if I set it rich or lean. Any help would be appreciated.

Mods: Walbro 190 rewired, EvoIII 16G set at 17psi, FIC 650CC injectors, 91 octane fuel, stock FPR, stock SMIC, 3" catback exhaust.

Those are what my NE points are on my 1990 TSI AWD, do you have an A/F gauge or possibly a datalogger to run a check on the O2 sensors, that would definitely help on your tuning and will be about the only way you can tune the car right, or should I say to get the max power out of it.

A/F gauges is actually useless in tuning. Unless it is a wideband.
The best bet would be to get an actual O2 voltage monitor or an EGT gauge with a fast acting probe like the one that TRE sells.
The O2 voltage is great for tuning at WOT, but useless at tuning part throttle or anything other than WOT.

i had all KINDS of problems tuning with the fic 650's. i just could not believe it was the injectors, because they were brand new. finally, after pulling the boost, and running several logs at ONLY 15 lbs boost, HELLA knock, and 90+% duty cycles, i ditched them for a set of denso 660's. ALL THE PROBLEMS WENT AWAY. i even had a chip to compensate for the increased dead time in the delphi pos injectors, even with that chip still in the ecu, it ran/tuned WAY better with the denso's. now back at 18 lbs boost, duty cycles are in the high 60's, and no knock. further cleaning and flowing(remember-these were NEW injectors) showed 2 of them to be WAY off, and they came back in spec after the cleaning.
even tho people say the car runs without an adjustable fpr, when i first installed a bigger pump(3kgtvr4), egt's shot up to .99 and sometimes higher. i had made NO other changes. i then installed and adjusted fuel pressure back to stock, and egt's came right back down. i bet your car is going open loop because the regulator cannot keep the pressure down. at wot this probably wont make a difference, but on stuff like idle and part throttle it does. also, when you abruptly lift off the gas, it probably dumps fuel, too. you should get an afpr.

I thought also that it might be my FPR and so I have one on order. (FTS AFPR) I never had these problems with tuning until I installed this set of 650's. I get erratic fuel trims. One moment I have it set perfectly 0/0 than I see it -3 (Meaning rich) When I drive the car really slow, like as in slightly hitting the gas to move the car a bit, My logger shows the STFT's going all the way up to sometimes +17 (Lean) but hitting the gas a bit more it would shoot straight down to rich.
Now WOT is even harder to tune so I am waiting on the AFPR to see what pressure I'm getting (Bought a Fuel pressure guage)and fix it to 43.5psi. (If its ofF) I have tried to lean it out at wot and I get a lot of flat spots and dips (Knock) with a high of 14 degrees at 7000. I tune it for rich and I get the same thing, flat spots and dips with a high of 15. I don't tune using O2 values but to give you an example of the fuel trim I'm running. when I say lean, O2 is .92-.94V When I say rich its .98V-1.V I have even tried to go in between.I too thought it might be the "NEW" injectors.
