On street tires I always run in PTM5. I never had any problems with it and on street tires it allowed me to pull mid 1.6 60' times stock. Now that I have drag radials, I turn everything off.

Now because you have a manual, maybe it is a bit different. I assume that because you're nose diving after spinning, the computer is trying to not let things get out of hand. If you turn everything off, you're going to have to try to control wheel spin yourself. Good luck.
