Thanks for all of the responses. I have my speed shop queued up to see what size of pulleys they have kicking around (mine is 4.0 inches) and we will also check out my injectors. All this talk of 10 and 11 lbs of boost really has me excited - don't know why I did not do it sooner. The 12.5s 5300 truck in particular gives me hope.
Will keep all of you posted.
Cheers!
