IDK, that wasn't my experience. Was kinda underwhelmed with the launch if truth be told, maybe it's because I'm use to a GTR which is pretty violent? P100DL is definitely faster 0-30 and 0-60, however, after 30 mph, the turbos are spooked up and it's like someone smacks u in the face.yes...
even my passengers all agree its very noticeable.
The first month i got my car, i did a take off in all the modes and then used ludi+ launch. (well this was when we had to preheat the battery)
And im telling you, you can scream fine up to ludi+ , but when i do Ludi+ launch, there is no scream... its a frantic grab at the invisible coat hanger and then the force pushing the arms back on them.
And i have the pissed off girlfriend and fear induced friends to prove it.
But back to the original question, there doesn't seem to be a huge difference between ludicrous and ludicrous+ on launch mode.
