I had an 06 with twins,port/polish,90h.p. nozzles,fire ringed,arp,cam,stiffer valve springs,fluidamper, and all the other good crap, but my suggestion to you is before you look to hit that h.p. you should get water meth to control your exhaust temps and perhaps a aftermarket injection pump or twin cp3's. I had an edge with attitude that was supposedly 160h.p. stacked with a smarty with the tnt-r software that was supposedly 230h.p, but my main issue was fuel pressure. Everytime I tried to turn my chips up I would loose fuel pressure on the rail. I had the dual fuel line from the injection pump as well. Theres my 2 cents worth.
