yup, thats kinda what I was thinking. When we went for the GTG Stewart was running 14.06x's but the same night I got my 15.1 he ran his personal best of 13.80 with no other changes. Lines up well I guess. Now I gotta make mine a 14 sec truck without cool weather.

your truck should run 14's in the weather we had yesterday IMO. theres probably more left in the tuning. did you do any weight reduction? just work on the launch some. i was able to get 2.18-2.20 60' times consistantly with the stock torque converter on the factory tires. i always stalled it to 1,000 and just roll into the throttle. youll have 14's soon

I forgot about the ET streets.
I still was hoping to break 14's when I got there, it was alot warmer and more humid in Baytown than the northside though. But I agree, more practice launching will get better times overall. I like the idea of rolling into it from 1000.
This is with no weight reduction on 1/4 tank. I weighed in at 5030 lbs with me in it. I don't wanna take anything off.
I felt like there was a little more in first gear then it shifted, I think it ran out of breath at the top of second, and third gear it goes woof and turns into a dog crossing the traps. Shifts are set at 5400 rpm, and from what I remember rpms dropped around 3000 or more between shifts.
there i feel better now. take off and little more tune and similar air prob gets me 14.8x-14.9x.

Yeah, I'm sure the 4.10's are letting you run out a little up top, but I agree you can get there. I just went back this past Friday to Charlie to update my tune. When he first tuned it, I had been running 87 octane so he had to bump the timing down a little to get the detonation to stop, but when I went back he was able to bump the timing back up another 2 degrees since I have run a coupla tanks of 93 in it. It pulls much harder now, it might help to get back there and let him add a few degrees of timing. Also, how much torque management are you running? He could prolly pull a little more of that out too.
He's got mine shifting at about 5800-5900 and its pulling good, IMO that 5400 rpm shift is quite a bit too low.

the 4.10's are probably why you feel it fall on it's face in 3rd. I know mine doesn't pull well when it shifts into 3rd at 75mph.....but it picks back up around 85-90mph.

Yeah, stew, whats up with the 1.18-1.20 60' times. How the hell did you manage that ****. lol.
Now if you ever upgrade to an aftermarket performance cam, the 4.10's will pull harder for you, cause you'll be making more power up higher in the powerband. But for a stock cam, 3.73's are the best overall choice IMO.
