2017 Silverado Z71 Double Cab 5.3 4x4

Gorske · April 2, 2017

Went to the track for the first time and I'm very happy how it went. Mainly focused on getting a stock time slip and quickest tuned 93 octane pass. It was 55 degrees with a 10mph head wind. I had a 1/4 tank of gas, full street weight. My truck with me in it is 5500lbs with 3.42 gears and 265/65/r18 wheels and tires. Stock was 15.20 @ 89.86 with a 2.13 60 ft. Quickest pass was 14.64 @ 93.42 with a 2.08 60ft. Stock pass was stalled to 2400rpm, launched in 4wd, left in Drive, with Traction Control off. Tuned passes was stalled to 2400 rpm, launched in 4wd, manually shifted to 6200rpm, with Traction Control off. Next weekend will be e85 passes.

If I'm reading your post correctly, you made a pass with your truck bone stock without a tune, and then "tuned" your truck at the track and made additional passes all in the same day? What tune are you running and what mods if any, are you running?

The person who tunes my truck was there at the track with me. He uploaded the stock tune file and after I made a stock pass he uploaded the tuned file. I just have a K&N drop in filter, Spintech 6000 Muffler, and a Klug Performance tune.
