PJG56,

Try larger rims and tires. I have around 400 hp and 400+ lb/ft of tq in my 560 SEC and I can get pretty good traction from my 275/40/18 Kumho Escta Supra 712's. New rims and tires should do the trick if your still on stock rubber. Heck, if I were running stock rubber, my tires would spin till I hit 100 mph.

My E430 sport feels like an absolute slug compared to my supercharged SEC! I guess it is relative to what your used to drriving.
