Aww come on, mine in valet with you foot on the floor smokes very little and makes 565 at 70 psi and I can actually tune it down to 55 in valet, it is more than responsive. Now I'm not saying this setup is the best but it's real hard to beat, guess I just like the quickness of the 40 and the charge of the Big Brother. You need to get someone to try the B/B, most would be fooled by is spool time.....stupid fast!

When the smoke laws start effecting me I go to a common rail!

With the setup that I have...I can at will at low boost leave a trail.. I just watch my right foot until the boost comes up to about 6 lbs and then I can go into it harder.
Things can get a little dark if I dont watch what I am doing. And I am still running the stock 215 injectors..
