I ran 15.1 in my crew cab stock 5.3 3.42s and 14.5 with a cai and tune but now it wont hook without feather footing from the line

Think once im finished with the suspension on my 2013 GMC im going to sell it this Fall and buy one of those newer trucks..... I think black rcsb 5.3L lowered 4.5-7 would look killa on 24s. :-D

2006, RCSB 5.3L, 60' was 2.33, 9.9 @ 1/8 mile, and 15.39 @89 was 1/4 mile. Even though truck is 100% stock(other than a FM40 muffler on stock pipes.) I was pretty disappointed considering, nearly sea level track, and it's a low mileage, 2WD w/ 3.73's and posi, and no tire spin issues. I launched it several different ways and this is the best I could come up with. It FEELS faster. lol ,crossy

2019 Silverado 1500 LD 4x4 here. Just got a dragy performance meter and just filled up on E85. Truck has longtubes, off-road y-pipe, custom single 3” exhaust, l86 intake manifold and ported TB swap, custom 4” intake tube to stock air box, aem dryflow filter, 160* t-stat, ngk iridium plugs (1 step colder), and my custom tuning. I’m hoping for a 13.

Wasn’t far off from what I thought I was running. Just punched it off idle and it was a little lazy with slow shifts. I will make some tune adjustments and see if I can get a 13.

My 18' single cab does 13.5-13.6 @ 102 all day... not too bad.
