Hit the 13s tune only!

[Gorske]

Took my truck to the track today and finally hit the 13s! My best two times were 14.016 @ 96.38(1/4) 8.925 @ 76.99(1/8) 1.94 60ft. and 13.967 @ 97.05(1/4) 8.915 @ 77.76(1/8) 1.96 60ft. vs the stock time of 15.219 @ 89.86(1/4) 9.703 @ 70.46(1/8) 2.13 60ft. which I think is a huge gain for a 2017 Silverado Z71 Double Cab 5.3 4x4 that weighs 5500lbs with me in it 3.42 gears, 265/65/18R wheels, Spintech 6000 muffler, K&N drop in filter, e85, and most important the Klug Performance tune. It was 47 degrees today and a DA of 865. I launched the truck in 4wd, kept it in 4wd, and manually shifted it to 6200 rpm in each gear for both passes. He thinks we can still get another tenth or two from some more changes. I am very happy with how the truck is now. Just shows what these trucks are capable of.
