are the torque limiters tables used on GSR ? because I get very bad launches and the RPM drops to 2500rpm

Airflow / Torque won't bring the RPM's down, it just cuts boost to wastegate and makes the car idle high, RPM dropping is probably from bogging the launch.

you mean clutch slip ? No I don't have clutch slip. I also completly disable the ASC
I wait for the stationary rev limiter to reach 2-3 times then I dump the clutch, sometimes it starts hard with a lot of wheelspin.
well if the torque limiters cuts boost then it should be reason why it does not have enough power to break the traction

Does it throw a cel and put you in limp mode? (idles high)

Then it's neither the Torque nor Airflow limiter.

It is very annoying that sometimes it launches hard and most of the times it drops the RPM and I get 0-60ft in 2,3sec., in the same location on dry tarmac

Are you sure you just aren't bogging the launch?

What RPM are you launching at?

I launch the car from the stationary rev limiter 5400rpm, should I raise the staionary rev limiter?
I am not sure what you mean with bogging (I can't speak very well english).

You are dumping the clutch too fast and when it grabs it brings the rpm's down.

You need to be able to slip the clutch a little to get the car rolling and then let off the clutch completly. Don't slip it too much or you will burn/glaze the clutch.

Last time when I let the clutch slip I got a lot of clutch smoke (It's a stock clutch on a tuned evo), I don't know why is this problem on evo, subaru's starts perfectly if you dump the clutch.

I wonder why the guys from Vishnu are talking about a limiter on GSR

And if Pathak had removed the Evo's electronic measures that protect the drivetrain, which limit engine speed during standing-start launches, the quarter-mile would have been even quicker
Disabling the Evolution's stock drivetrain protection would make for even quicker launches, while tweaking its electronic throttle would make it more driver-friendly during daily use.
