Any dually's out there?
 

Was wondering if anyone with a 3500 mega cab 4x4 dually has ran the Quarter mile and what there times were. Thought with all the work I've done check sig would have done better than a 16 flat? Any ideas or am I expecting to much from a 11,000 LB truck?

11,000 lbs?? Mine weights 6600 empty.

your tires are killing you and the lift doesnt help whats your 60 foot times are you doing 4x4 boosted launches there is alot to do down on the low end to get the good times at the big end

Guess the weight is more like 8000 not 11,000. Don't know the 60 ft time didn't actually goto track the edge has a performance test for 1/4 mile it starts timing when the truck moves and uses the odometer for distance figured its close to accurate. I was in two wheel and from a dead idle. Does that make that big of difference? The tires are still going to hurt me even though I changed the gear is that because they are heavy?

yes, rotating mass

also is your speedo correct (100%) that will throw off the edge, boosted launch will help a bunch as well, add all of the above together and it could be worth 2-3sec.
