guessing my 1/4 mile
after some "safe" tuning...15*WOT, 11.5 AFR...and I have the Alcohol turned off right now. I did a 0 to 100mph blast off. I notice that alot of trucks 13.5 to 12.5 times are in between 98 to 103mph for the 1/4. My friend has a wrx and crosses at 97mph and pulls down a 13.8.
Looking at my HPT Scan...I start moving at 8.722 seconds and hit 100MPH at 21.561. Couple quick clicks of a calculator shows 12.639 seconds to get to 100.
I know depending on alot of things determines different things. I know I know you can run under 100 and barely break 13.5 and you can run a 100 and get a 12.5....lots of stuff, gears, stall, blah blah blah.
Just trying to get a feel. I have a GTech,but it said at 98mph I was at 13.7...not as per the HPT scanner....I was at 11.928 at 98mph. I don't have my weight correct on that GTech.
Just seeing where I stand now...once I get some alocohol, tune for it, and calibrate that MAF...I'll see where I stand again. Whatcha guys/gals think?

we seem to have similar setups, or will when I am complete with my install. How much does your truck weigh?

In street trim most ECSB 4x4s should weigh around 5300-5500lbs.
my truck had the following done:
No tailgate 45lbs
No rear seat 65lbs
No trailering gear 35lbs?
1/2 tank of gas
stock wheels/tires
remove my subwoofer boxes
and a few other things I cant remember lol
When I was N/A I had raceweight down to 4900lbs. The turbo FMIC and other crap weighed me back down.
The scale may not be 100% accurate but its consistant and located at the track.

So back to my thread...it's all about me
...with that knowledge(weight) I entered 5650 into the GTech for weight and recalibrated and STILL ran a 13.6. BUT, It never dawned on me before...I have been so worried about safe tuning, broken trans, converter, vibration...(I had a warped/bent flywheel...YIKES) that I never bothered with trans tuning. I looked at my GTech and it has me shifting 3/4 at 4700!!!! What!?!?!? 
I have the rpm WOT set at 5850. I can't remember the speed @ WOT....hmmm....I thought BOTH have to be passed before it shifts. I don;t doubt I am losing a second or at least a half second with the way early shift.I am so good at turning general threads into tuning threads and vice a versa...LOL

Judging my old set up vs yours and your extra weight, I'd say low 12's. An 11.90 would be sweet!
I know mine had a 12.20-12.30 in it with weight reduction.
