Yes, it gets to 120 mph almost 2 seconds faster. I remember I was able to get to 120 mph in about 14.8 secs. Now I can get it to 120 mph in 13 secs.

Edit: I just watched my video from 3 months ago and I noticed part of the beginning of the video is slightly cut off. Most of my launches start right at idle. The one posted 3 months ago shows it from 2.1k rpm and up. I remember the temps during that run was in the low 30s. It felt great! The new one I posted with the tune, the temp was in the mid to high 50s. I wonder how it will run when temps drop down to the 30s.....

Temps make a huge difference. At the track I normally get up to 210Km/H running up the back straight but my last day out was very cold, allowing me to run up to 230Km/H. Everything the same, just much colder temperatures.

I'm not a drag racer nor have I ever taken a car to the strip (flame me if need be) but instead of raising the rev limiter -- so you're not bouncing off of it as you pass through the gates -- could you not run a taller tire? I don't know how much there is to spare but what would be the results of a tire .25" to .5" taller? No differences in where you're at as you pass through the gate?

A taller tire will probably have a larger rotating mass and will also behave like you have a taller final drive ratio. Both counterproductive in drag racing, you might be able to cross the line without bouncing off the limiter but you'll also be slower getting there.

6800 rpm = 113 mph w/the stock 255/35 x 19 rear tire.

In 2012, Caymandiver used a 245/40 x 18 drag radial for his 11.87 @ 119 mph 1/4 mi., crossing the traps in 5th. With the 7200 limiter, I'm gonna go with a 265/40 x18 & try shifting @7k.

Quick question for anyone who can help me, I noticed in the video that the traction control was off the whole time. My traction control doesn't stay on after I pass 20mph or so. Is there a setting that can be changed or any other reason that might cause that?

I start the car while pushing parking brake and regular brake

- Pump the parking brake twice while holding the brake
- Hold it on the second hit and then push the brake pedal twice again

It takes all of about 5 seconds to do LOL.

You need to told the traction control button down for a few seconds. It'll turn everything off except the E-LSD

Apparently holding the button down doesn't turn the traction all the way off but the pedal dance does. Interesting...

WHEN U HOLD IT ABOUT 5 SECONDS ONLY FOR TEMPORARILY, BUT WHEN U DO PEDDLE DANCES, IT WOULD DO IT WHOLE ENTIRELY UNTIL YOU RESTART THE CAR PIE MUST BE A NEWBIE LOLZ

Has anyone else experienced VSC light coming on after the ecu installed back on the car? Mine came on twice but went away after I turned the car off and back on.
