I finally pulled a (barely) 12 second run with my 2WD 2020 STX Screw with stock tires and a 3.5L with 5star 93 performance canned tune. Only mods are tune and Stiffler's traction bars. The collision detection was going off and the truck was braking and bucking for the first two runs. Once I figured out what was happening, I turned the autobraking and traction control off. The truck responded amazing, I just need to get my right foot dialed in a bit more, lol.

 

Thats impressive for a tune only 93 truck. Congrats.

 

Really good. I've seen Mustang GT's that don't make it into the 12's.

 

Thanks! My STX's weight helped a lot because of the lack of power seats and other heavy features.

 

nice! might be a mid 12 second truck on a tire

 

easily... even if you got it down to a 1.8 60 you're lookin at a ~12.50 slip

 

That's their base tune with no revisions?

 

Seriously. My stock 2006 GTO was a 13.3, maybe 13.2 car in mineshaft air. And that was 1000 lbs lighter and an aerodynamic marvel compared to the OP's truck.

 

2wd’s are tough to get that low ET.

Here is a 2020 3.5 XLT Screw 4x4, Tune only, 5 star 94 tune, no revisions, custom shifting.

 

Oh, yeah, well I pulled off a 5.6 to 60mph using my butt dyno when I first installed my 93 perf tune from 5*. LOL. 'Tis fun.
