Default 05 Silverado ext 1/4 mile time

So I have an 05 ext cab that I'm wondering what it would run in 1/4 mile. It has a lq4, tbss intake with vette tb, 30lb injectors, long tubes, 180 thermo, and mail order tune so It def needs fine tuning but what should it run on quarter, low 14 high 13? Thanks for the input

Vehicle weight?

Tires and gears?

Lots of variables here so it's hard to give a time. Not knowing how much power the engine makes is tough too.

I know but this just a best guess bc only running it will really tell bc you could have 2 identical trucks and they can run diff times
Right now its stock tire size and 3.42 gears but in a week or 2 I'm going to 3.73

I really doubt it.. my 4.8 with less mod than i have now ran 15 flat to 15.2.. I know 60 isn't gonna be great unless I had slicks bc it it spins thru first at half throttle.. but I am getting posi with the 3.73
