Hey guys need some input here. So back in the fall I was running a 13.1 at new england dragway. This was completely stock, with about 18k on original tires, so tires weren't great.. 60ft was 2.2, felt tons of wheel spin. Now, last weekend I went back and ran 3 runs best was 13.2. With borla exhaust and toyo r888r tires which are sticky and launch hard!! I felt like I had better launches but was still pulling low 2s 60ft? What is the key here... i see people running high 12s consistently stock, this car should be running at least a mid 12 with these tires I'm thinking... the fact I'm running worse times has me confused. I'm a noob at the track so idk where I'm going wrong. Is my car just slow?? These runs were done no burnout... also I tried doing peddle dance to turn off nannies to do burnout.. but e brake light does not come on anymore. Help please lol
lower tire pressure to 22psi
put on sport and turn off traction control
do a good burnout
-the car will put you into 2nd gear slippery start mode. To get out of that mode, drive forward 20 feet to unlock. Reverse back to starting line
brake torque before tires start slipping
leave it in auto

Good points. Tire pressure is very important. In a straight line, lower pressure is better since sidewall stiffness is irrelevant in a straight line. When I ran my other car, the best results I got were with 19 psi in the front (FWD car) and 35 psi in the rear. For RWD, lowering rear tire pressure will give maximum straight line traction
My best time on stock tires was 12.4 stock with borla. here is what you need to do
