So ive tried to look around and find some good information on Launching or trying to leave with a decent 60 ft and the best i have found is 3200 rpm launch from @Mvaccarelli01 but dosnt seem to work for me. Thanks in advance to everyone !

Currently i have my launch set at 4200 to build some type of boost off the line but i just seem to spin, ive tried performance mode and its too slow to kick the power on due to the spool, leaving off the foot brake is even worse. Seems like i might have to wait for MHD's antilag at standstill to come out.

Anti lag will help but it’s a double edged sword as the DCTs are fairly harsh when they launch.
The launch RPM is changeable and if you’re lucky someone here might know about the DCT launch subroutine in the code and there might be some benefit to changing how that works.
Bottom line… DCTs are great for drags if you have abundant traction. Anything less will make it hard

The plan is to run 8 or 10 psi on 1st gear with antilag and then ramp in the boost with second gear etc

Yea the stability control kinda robs you of alot of power using LC

I have launched at the strip about 250 times, and the best method with all the xHP settings and everything tested, just mashing the peddle and getting the right boost by gear set worked for me. All setups will work different though and I think the anti-lag is going to be one of the best methods when its ready.

I don't think anti lag helps much off the line. Quite a few JB4 users have tried it and general consensus is by the time timing recovers, its the same as smashing the gas for given traction, etc.
Myself included in testing.
But will see if MHD acts any different when released.
Also this is speaking on autos, DCT may behave differently on off the line anti lag.

what type of 60ft do you see by doing this and how much boost are hitting in 1st gear?
