Damn both of your trucks run damn good! I am kind of suprised the 4x4 Silverado ran THAT quick though... wow...

Your truck is a runner as well, my FX4 60'd a full tenth quicker then yours yet you had me by 4 tenths and almost 4 mph at the stripe..... Although when I ran mine was in the middle of Aug. so I had around 3500' DA...I also ran it on the 33x13s which definitely killed a couple tenths or so...

I hope to squeek a 14.99 in good Winter air...

BTW did you try running it in Tow/Haul mode? If so did it improve?

The other lane was my brother's 2011 Chevy 1500 crew with the 6.2L engine and 3.73 gears, thing is fast. We both had my own tunes. His best was 14.05@98mph. He didn't make much more power on the dyno but has much more under the curve and he's lighter and lower although it's 4wd as well. I still like the Ford better overall.

I put the boss intake on my truck with 93 tune. my 60'foots were the same as yours . I was wondering if the boss hurt my 60"foot . I have an xl 5.0 screw 2wd 3.73 gears my best pass yet is a 14.32 at 98.9mph. Im hoping to get the 60' down some how to get closer to the the 13's

I shot this with my Droid and it sucks but not easy driving and filming!

I agree with you about that 6.2 gm motor. My brother has a 09 yukon denali "Suv" with that motor . Bone stock it ran a 14.68 @94 I was very inpressed !

For 1.2 liters/73 cid less than the GM engine, that's still an impressive run.
