Ahh I see. Well get one more clean pass in with the timing pulled. I bet your pretty close.
He needs to pull timing since he pulled these out at the 1/8th mile.

Wideband reading, Weather conditions + pics of the plug from that run is really good info when it gets time to up jet.
Just trying to make sure your as safe as possible and have as much information as possible. Doing good tho sarge, should be spraying 300 soon.

Its a good idea to record that information.

May start looking at adding a Nano setup.
I'll make another logged pull tomorrow and take pics of the #3 and #7 plugs.
I appreciate everyone's help.

They looked exactly like the the pics I posted. Absolutely no change.
I just went for a run to see if the A/F looked better after the Boost-a-Pump and it seems to have fixed the fueling issue. I no longer get the a lean spike at all. A/F drops from 14.5 to 11.63 in 3/10s of a second and bottoms out at 11.03 at the end of the run and that includes a shift. I did get a slight rich dip during the shift to 10.89 but came back up to 11.89 at WOT and settled to 11.03.
Now I can make a plug run and get an accurate read with the fueling straightened out.

Good deal on the boost-a-pump idea we talked about. Saved you some headaches im sure.
Keep me up to date sir.

Hell yeah big props to you for suggesting that. Man I feel so much better not living on the edge now! LOL.
Wish i could see the pics but sounds like you got a handle. also remember as the weather gets better you not only need a little(jsut a little) more fuel but the timming will need to be taken out.

That timing mark to me looks like about max I'd want to see after a 1/4 mile hit, they're right on with pulling 4 more then you already have.
Fuel, that may look better with the timing pulled but if you can add a touch back easily do it.
No need to burn that beast up on the fist couple hits.

So now I have a full bottle and fueling fixed so I'll go to the street I do my runs on and and swap out plug 7 since it is my hottest cylinder and make my run with little to no driving on the plug. Make the run and pull the plug. That's about as accurrate as I can get it.
Prolly tomorrow AM.

All of the pics are pretty much a wash due to fueling problems. I kept pulling timing and there was no change in the mark. Now that I got a boost-a-pump in and no more 2 second lean spike I can get a better read. I made one run on the last of the bottle after the boost a pump was in and A/F was right at 10.89-11.08 and no more lean spike. Now it's rich. I didn't pull the plugs then as it was at night and I was just seeing if the BAP made any difference and it did.
