Have any of you guys taken the new model '07 Silverado/Sierras to the track yet? I'm wondering how they run compared to the 1999-2006 5.3's, specifically. If you have run your '07 truck at the track, please post your times and specs.

thanks

 

Here ya go..

nice thread ,
these guys need to slow down with their typing and spelling and give
a full signature.
my 07 6.0 runs good but still needs a the tune finished.
above 3000 rpm it pulls close to what my 04 5.3 radix did, below that it's hurry up and wait.
tune is the big deal, imho

 

drove a 07 max and know what you mean.. that thing is horrible down low.. i bet a tune would make it feel stroooong..

 

the vortec max are killer with a tune...i've seen an ext cab max with 20s and tune only hit a 14.5 and a 4door max with 24s with tune only hit a 14.7...not bad if u ask me, fast and rolling in style!!

 

I'm going to free up some time next week and go run the truck again. Hopefully it's not raining. I went 15.3 on stock tune. I don't know if it's because it was a WORK TRUCK or what, but since it's been tuned it feels like a missle. Times should be much better.

 

12.61 07 here

 

DA is 2,245 feet at the track right now. I'm leaving now for NPR that is close to the DA when I ran last time. this should be a good test.

 

see drag racing section for my results

 

i went 14.0 with k&n cai, asp pulley, borla exhaust and tune....then i went 13.7 with stall, a headers and 3" exhaust but when i ran that my g80 let go so it only hooked one tire and the other spinned..
