to answer your question i currently only have 420rwhp with 421rwtq, it is on a very poor tune, wayyy rich, i asked the guys that will be tuning it and that is their input, its obvious, black soot all over the back of the car after full throttle, granted, it should be somewhat rich so i dont fry the seals and have muchas problemas lol but not that bad, so with a good tune, and the intake swap, id be up around 500i d say go for the tunes if all your adding in ls6 intake to your system your already extremely close to 500 personally i would take the tunes..
