man i feel like you gave up too easily...
what a waste of time and money. if you would have just got it tuned right, there would be no problem, its not like you had to run 10psi anyway. 6 or 7psi in a light ass truck like that would have been pretty quick.
i cant tell you how many problems ive had getting my car running right, but i kept at it and its running almost perfect now.
its very disappointing that you just gave up.
