My only upgrade is a Takeda Cold Air Intake, I manage to Pull out a 14.212 in my best pass but I only did 2 pass due to track being pack. The car could easily hit a 14.1 or 14.0 if I improve my 60Ft but the stock tires suck. I didn't spin much at my first pass but didn't brake boost that much in the 2nd run I brake boosted much more but spun my front tire a little and couldn't improve. I'm certain with a good 60FT the car can be able to run a 14s Flat. Which is amazing for a car that weight 3960 with me in it. Im going to Flash the car in time coming and would highly guarantee a high 13s pass just like the car is now. With a JPipe+Catback Exhaust and a good tune the car should be running a Low 13s in my opinion.

 

1st Pass

 

Interesting. You should consider indicating what kind of TLX you have. I know it's a V6 just because you mentioned j-pipe. Is it the awd variant?

 

2015 TLX SH-AWD, Stock Tired and had more than half a tank of gas. I'm positive the car can run 14.0 flat just like it is right now.
