On a fairly low power low grip RST i cant see how its gonna help much.

Its great for big turbos as it will get the turbo on boost before your going anywhere, but traction is always gonna be an issue as you on wide open throttle, and as you not got a huge laggy turbo it not helping you there either.

On normal road tyres i reckon youd be better off launching in 2nd if your using launch control, as im sure you can have it set to some revs where it wont bog down.
