Roush pully size

I have the Chicane pulley. I see 10-11 pounds of boost instead of
the 6-7 I saw before. I did need to go to a bigger fuel pump and chip since
the car was going lean with just the pulley change.

Also, make sure you are truly getting to WOT. When I first got my car, it was a DOG.
We checked and found that when the pedal was on the floor, the throttle body
was not opening all the way. A couple of spacers on the throttle cable fixed that.
