Default 3.8 time guesses?

What do you guys think my 3.8 auto with 3.73s, T-Loc,(obviously a tuner as well) and a J-mod would make on the 1/4?
How bout 4.10s? What are stock times? Let me also remind my cars a vert so slightly slower. Im trying to figure out my final plans performance wise for my car..

If you plan on the gears and the tuner, I honestly wouldn't even bother with the j-mod, just have the tuner up the transmission's line pressure and shift points. My auto slings me pretty good through the gears, no need for the j-mod when you have a tuner. If you are going with gears let me know, I have a set of new 4.10 gears for the 7.5 rear I have been meaning to sell, shoot me a PM if your interested. I have 3.73's on my v6, I wish I would had gone with 4.10's.

Jmod is much better then a line pressure bump.

Stock depending on weather you are looking anywhere from 16.5-low 17's. Fastest my car has gone was 16.64 slowest was 17.0's. And my mustang is stock except for the air silencer being removed, but i doubt that did a anything noticeable power wise, just made it a bit louder.

2000, and if i do the gear swap, itll be just grabbing a 8.8 rear end probably, much cheaper.

Leme put it like this, what would be my times as of right now, with just plugs wires and springs, and what would be my time with a 8.8 rear end with 3.73s or 4.10s plus J-Mod and tune?

Right now, I'd probably say 15.6-16.0 and with gears and tune 15.1-15.5
