Hey guys, so I got my 2006 xr6 turbo ute about 3 months ago and its going great. When I bought the car it came with dyno sheets which were only 2 months old saying 257 rwkw, the guy I bought it off said its had injectors, intercooler, and tuned to 10 psi, its got an exhaust also but not sure about the cat etc, My question is how do I get to 300 rwkw if technically with the mods it has it should already be so? Thanks for any help
