Almost but not quite
I guess I was just spraying air when we tuned the truck last week, with a full bottle today I was getting too much knock to make my mark but I still made a new best.
1st run I let out of it as soon as it hit 3rd. Too much knock.
1.714 60'
7.619@90.393 1/8
12.083@107.937
2nd. I upped the meth a crack, still had some audible knock but stayed in it
1.72 60'
7.657@89.642 1/8
12.080@110.509
3rd. More meth AFR was 10.7 still had knock, new best.
1.733 60'
7.679@90.236
12.073@112.275

Man, that truck is flying on the top end. Its just a matter of time, you will dip into the 11's.
Hey, you got some ***** staying it it with audible knock (being blown and sprayed)!!!
Nice work man. That motor is one stout power plant no doubt.

Damn buddy so close. Congrats on the new times. I've seen my fuel pressure drop and AFR go lean on the big end, tried running on a 1/4 tank... no no, and stayed in it. I have never heard audible knock and don't know that I would have the ***** to stay in it if I did. I am beginning to think that 4.10 gearing is another key to getting these heavy pigs to go into the 11's.

DAMMITT...I responded to this earlier, hmmm.
Anyhoot, Hell yeah Mr 5.3! Yeah on the Zippy question? You have race gas in there? You still pimping the 50 shot? LOL I agree, that first run was it. 12.08 with 107MPH. LOL
I'll say it out loud...more cubes might do it to. 
Or 75shot.

Yeah the cubes too, but comparing times. You guys have the HP to pull it, based on the MPH but are falling short, compared to my slips, on the bottom end. All my 11 second passes I've gone at least 7.5 through the 1/8th. Gearing helps that.
