I think the only reason the wife can get a 1.7 60' on these tires is the track prep is real good here. Here is a video of her best pass of 13.00@101mph, this was at about 10psi of boost.

I honestly don't see the 60' being your problem. low 1.7's are good for you, you need to work on the 1/8 MPH, your truck needs more horsepower. You are getting off the line very good just running out of steam. You have enough turbo for 5-6 more MPH.
hahaha
I was just re-assuring you that BLKLMM was indeed a very experienced racer, nothing more
the toe setting thing is a crucial element cuz as the truck launches and the front end lifts, the front tires "toe" in, or point in to the center. if you lower the t-bars the toe setting will actually start to point out the lower you go, and this is helpful for when the truck launches cuz as the front lifts the tires won't toe in and create friction drag or bind. If you lower the t-bars and have an alignment done, the benefit of having the toe setting pointing slightly out will be lost and even though the t-bars might be down you'll still get the dreaded IFS pigeon toe or "toe in" at the launch and while traveling down the track under throttle
removing the T-bar bolts completely will get you the lowest and some guys even cut the jounce bumps on the LCA to get even lower, the lower you go the less lift/weight transfer you get to the rear and you'll receive better contact/traction to the front tires with less chance of wheel hop.
it was mentioned that you can also run the rear leaf pack clamped, but I always thought that was a sled puller thing:dontknow:
looks like that was a pretty clean run, nice:thumb:
I'd start with some QA1 double adjustable rear shocks and a set of cal tracs, maybe down the road get a set of slicks or depending on what the daily duties of the truck are just run some cheater slicks and see what that will accomplish.
you still running the emissions crap? cuz I noticed a pretty nice increase of throttle response from a complete EGR delete with the 3" IC cold side tube, that could help your overall ET not sure if it'd help the 60' time all that much

I do take the bolts out so it is as low as it will go, I have the EGR blocked and shut off but still intact. I plan on a SDP EGR delete and then possibly twins down the road.
Yes.
3000Us, 28* of timing, if your still trapping 101mph and going 13.0 you have other problems assuming tuning is 100% smooth. I wouldn't worry about drag radials or front end parts yet as your truck can 60 good enough for 12's without a doubt, I'd concentrate on getting more power of the truck. :thumb:
With your exact 60', (1.74) I ran 8.001 in the 1/8th and a 12.71 @ 106 in my LBZ with stock injector/turbo/cp3. It's possible, you just flat out need more horsetorque
Time doesn't start until you break the beam leaving. You can sit there for 5 seconds its going to show what the truck actually ran once you left then a 5 sec. reaction time, but your going to lose by 5 seconds.
Yes.

Sounds about right. Did you just make up the word horsetorque :roflmao:
The GF did when I taught her about nitrous on the truck and when to press th button, then she got horsepower and torque mixed up and said "horsetorque" :roflmao::spit:
LOL i would have died laughing if my GF said that. That is awesome, im so gonna be using that from now on! :spit:
I've been on this site for awhile and will go on the record that no better word has been dreamt up imagined, made up, accidently or on purpose.
Yes.

Thanks, now the wife is saying she needs more horsetorque in the truck so she can beet more boys
Hey Dustin you guys have a tune for me with more horsetorque?
Ok thanks, I will try that to start with. I also made a mount for my GoPro for under the truck so I can see what is going on front and rear:woott:
Did better at the track, the wife got the truck into the 12's with a 12.95@102mph. Her 60' is consistently around 1.7, she was leaving the line at 12psi and the truck was hooking well, going down to the test and tune on Wednesday to try some things out and do some data logging.
Here is a video of the rear end on the 12.95 pass, I will get videos of the front end up soon.

Here is another of the rear with a 12psi boosted launch.

And one of the front.
