I took my 2005 Silverado Crew Cab (5.3L w/3.73) to the track this weekend. The truck only has 700 miles on in and the only mod I've done is 3 inch Exhuast from Y pipe through a Hooker AeroChamber out of factory location. First pass right after driving an hour to the track was 15.80 @ 88.2MPH. Second Pass was 15.66 @ 89.4mph. Third pass was 15.61 @ 89.9 mph. I was kinda of suprised on the first pass because the truck stalled 2000 RPM left spin slightly then seemed to bogg down. On the second and thrid pass I didn't stall it as much (around 1500 rpm) and I didn't just jam it to the floor, instead I just smoothly and quickly put it on the floor. It felt as if it left alot harder but only showed a tenth of second difference in the 60ft. Over all I was happy with the numbers, I didn't expect this big Crew Cab to do this good.

I've ordered a Predator from Runnin With The Devil and a Volant CAI. Looking for some 15.20's in the near future.

 

sweet , since a guy with K&N and hypertech 3.73 but with 22s ran 15.9! nice times

 

Wow, that's kick *** for brand-new like that !!

Dude, don't waste your money on a Predator, look here .

 

Guess I need to get mine to the track and see what it will do.

G-tech said 13.90's with a 2.60 60 foot.....but who knows if that is right.

 

Yes you do 13.90's would be pretty darn good for a CC.

 

Soooner or later, I will go....Just need some time away from work

 

Yea cuzins 05 Crew Cab with K&N,Hpp3,3:73;s on 22's hit a 15.9 might go this next friday with originals brake those mid 15's

 

nice times on the crew cab

 

Best mine has done to date is 14.76@90.56 mph. With the mods below. I will be getting my headers and cam installed later this month, so we'll see how that works. I'm going to the track as soon as I get the headers and cam dialed in.

 

Well, I did consider going with the Nelson Tune but I didn't like the Idea of pulling out the factory computer and shipping it to them. I also wanted to be able to return to the stock tune at a moments notice if needed. By going with the Predator from Runnin With The Devil I can run the "generic tune" from DiabloSport, or I can get a Custom Tune from Runnin With The Devil. To me this is the best of both worlds.
