I just recently bought a 2008 fg turbo. I drove out of the dealership and drove straight to Genie exhaust and Dyno, in Perth WA. They fitted a 2.5 inch X force, stainless cat back exhaust and K@N panel filter.It was dyno'd @ 264 rwks and 355 rwhp. Due to a double booking they couldnt do a pre fitment dyno unless I re booked for another day. So, I said fu$k it, and just do the final dyno and see where I stand " I didnt want to wait". Going by what most people say, the fg xr6t puts out about 220 to 240 rwks stock standard. So...... I reckon that's a pretty good result for a non tuned car.
