I have been trying to get help off my thirdgen websites but I thought I would try hear since from the threads I was reading on here people really have experience in this stuff. Most of this info. has just been copied and pasted so disregard it sounding weird
Here are the mods/delted stuff that matters most in emissions:
race shorty headers
no cats
no mufflers
no egr
no evap ccp
no a.i.r
Also I use 93 octane gas all the time.
new plugs, wires are good, new injectors, stock fuel pressure and stock regulator. I am using the stock a/c delco plugs that my car calls for with stock gap. aftermarket msd blaster 2 coil. other things that might affect test would be I have a 2800 lockup stall, with the stock torque converter settings for lockup speeds, etc... someone suggested on another board that I should keep the converter unlocked for test which would be speeds under 70 mph i think, might keep my reading more constant.
Test 1: Failure all 3
-chip had injector constant at 22, and I just put in 24s.
-chip 8 base timing, base timing set at 0 on engine.
-stock timing chart as well as stock fuel chart I believe.
-fan 1 I turned off, fan 2 I believe came on with the stock fan switch in the head, since it didnt get to the redline in temp but was def. up there at least 240
-outside was raining and about 58 degrees outside and humid

Test 2: Failure 2 out of 3
-chip injector set to 26, and I have 24s
-chip base timing set to 12, base timing set at 0 on engine.
-stock timing and fuel charts.
-fan 1 set at 235, off 230, however while I set sitting there it got passed 235 it seemed and I got worried and flipped my fan 2 switch on, so the whole time the fan 2 was on and the temp on the engine was about 185
-outside temp was 65 and sunny

Just from those readings I am going to double check my fan 1 does come on, and I think I am going to up the base timing in the chip to read 20.
would it be ok to try and lower engine base timing to under zero?
From these readings what else should I touch, since all did lower alot.
Test 3: Failure 2 out of 3
weather was crappy today, not raining anymore but humid and around 55 out.
this is what i tried today.
new chip with engine timing at 0, chip base at 0
lowered max timing from 42 to 30, and lowered all timing -5 on the charts, probably didnt take out enough timing
injectors set at 24 which they are, and for the fuel charts -5 throughout.
1/4 of the usual 93 gas, 2 to 3 bottles of the 91% rubbing alcohol and a small thing of octane booster (i am getting desperate).
fan comes on at 231 off and 225 regardless of vehicle speed.

I guess I need to start over again, I dont think it likes to run hot??? At least the NO is always high when it runs hot, maybe I need to cap the temp to 220 and no higher.

test 2
test 3
I think my best choice to is maybe tweak the tc lockup some, set the chip base timing to 0 and -12 throughout the low to mid range and -15 middle to higher; set the injector constant to 26 again, fan to come on at 228 and off at 220.
with about 1/4 of gas i am going to add the gallon of denatured alcohol I purchased today and I think with decent outside temp and weather it might pass.
