Hello 12s!!! 2017 5.3 Z71 ProCharged
Well as of tonight I now have a 12 second truck. All the passes were brake stalled to 3200rpm, 4wd launch, 2wd after the launch, and 6200rpm shift points. Mods ProCharger P1-SC 10psi @ 6200rpm, Circle D 278mm 3200 single disc, Klug Performance tune, Black Widow 250 custom cat-back, Falken Wildpeak AT3 tires 265/65R18, stock 3.42 gears with a 6 speed, and full street weight of 5500lbs with me in it. Very very happy with my results from tonight. I can't say thank you enough to Zak with Klug Performance for all the hard work on the tune.
First pass: 13.04@105.07(1/4), 8.35@82.69(1/8) with a 1.93 60ft 75 degrees DA 1965
Second pass: 12.86@105.61(1/4), 8.20@83.61(1/8) with a 1.85 60ft 74 degrees DA 1893
Third pass: 12.88@106.81(1/4), 8.28@84.40(1/8) with a 1.95 60ft 70 degrees DA 1629
Final Pass: 12.86@105.46(1/4), 8.20@83.38(1/8) with a 1.82 60ft 70 degrees DA 1630

Thanks. Yeah I am not sure why that one pass the mph jumped like that in the 1/8th and 1/4. I didn't do anything different from the other passes. Maybe when the Audi R8 I was racing went flying by me on that run it boosted my mph....

Thanks man! Zak made some tuning changes and that's it. We had left the timing low, and didn't really mess with injection timing with the ProCharger. Tuesday night we made fueling, timing, and injection timing changes. I'd say we found the sweet spot for the trucks tune. Still a safe not super aggressive tune with 75% torque management. Going to leave the tune alone for now till the next mod 
Next step see how the truck likes headers and see where that puts us in the 12s. Mid to low 12s would be sweet.
