no I am running ppc long tube headers with random tech high flow cat's and flow master cat back system with vortech v-9 intercooled system at 9 pounds of boost. Prior to installing the supercharger I had a bad plug and was misfiring for about 10 miles and I think I damaged bank 2 converter. Do you recommend anything, I ordered a new converter for that side. what would be triping the heater performance codes since the system is intercooled and is there any thing I can do about it.

Yes, many have done that, but tuning can do the same as o2 sims, eliminating sensor 2 (rear)codes on both banks, Horist is right, dont mess with sensor 1 codes on either bank, bad. Vortech blower, no tuning? If you do not, you should, subtract the $100 dollars or so you will spend on o2 sims and you are that much closer.
