Took the truck to the track last night. (Edinburg International Racetrack) My truck is a 2003 Silverado RCSB 5.3. Mods are FIPKII, true duals, HPtunning, and TB coolant bypass. Here are the results.

First pass down the track I ran a 15.795 @ 93.59 w/ a 2.6 60ft. I was having lots traction problems (peg leg on 235/75r16 firestones), so on the next run I had to ease into the gas pedal so I would not spin the tire.

Reaction: .408

60ft : 2.486
330ft : 6.583
1/8mi : 9.895
E.T. : 15.101
MPH : 94.096

Last night the weather was pretty warm. So that didn't help either. What do you guys think? I know what my next mod will be. Can anyone guess? All feedback welcomed.

You definitely have a 14 second truck there, chech out my times with the current mods. I'm at a 15 flat @~90 mph. You have 4 mph on me and my 60' is in the 2.25 area.

Get a locker and go for it.

FWIW when I had 3.42's I couldnt cut better then a 2.3 even when launching with nitrous.

 

Thats true. 3.42s suck in the low end. They are designed more for saving gas than for drag racing. Although my cousin hit a 2.2 60' with his 3.42s. https://ls1tech.com/forums/showthread.php?t=326036. I'll ask him how he did it. Plus they are not helping me much because the tranny shifts into 3rd gear about 100' before I cross the traps.

 

try shifting it yourself....
