I think I was the first person to get these after Seb and it is by far the best upgrade I've done! I haven't updated my profile in awhile so I'm not sure what it has but I've got all the usual upgrades along with Sport 500 turbos. My goals were to have the best street set-up and I wasn't really concerned with dyno numbers or drag times and now I have absolutely NO LAG, the car is soo awsome it makes power off-idle all the way to redline. Eventhough I chose not to dyno the car Greg tuned it with a wide band and thought the car was well into the 500 hp range at the wheels! I recommend these highly to anyone with this car, you will be very happy!
