Those aren't bad times for a NA. If it's a TT you don't need RLTC you need some decent tyres and/or a lot more practice at launching.

You aren't running 19" wheels and tyres by any chance, are you?

Good for on the road fun, not sure for serious 1/4 mile runs though!

 

Like Jake said you probably just need some decent tyres.

 

All it does is hold the revs at a fixed set level, which is good fun.

 

For instance I've got mine set at 3000rpm. I stop the car and then press the launch button, put your foot on the accelerator - press it down anyway from 3000rpm to the redline and it will hold it at 3000rpm.

 

Let the clutch out and you're off!!!!!

 

The RLTC is great at sensing the wheelspin and controling engine power to reduce it.

he has a tt

sounds like he needs some practice launching a 6 speed. maybe he giving it too many revs off the line. keep trying lower revs see what works best. in auto i found 2000 revs was good on stock stall

 

do a search for all the posts he has made comes up with below
