I have 2 turbo chargers, 1 super charger, strieght exhaust, cherry bomb muffler, K & N cold air intake, NOS nitrous and only have 870 HP

twincharging (supercharger and turbo) is a waste of money.

Nice! I'm not into jap cars but 870 is nothing to laugh at.
I used to have one of these. Yeah, on board computer will help, as will bigger turbos. I dunno if I'd twin charge that engine, maybe take out the supercharger and just go with port and polishing the engine, and bigger turbos.
