i have the dual patriot springs and it want go above 15psi because of valve float from pressure on the back side of the intake valve. i have 2.02 int 160 ext. i have shimmed them tighter for more seat pressure and it worked for awhile but the spring got weak again. the most it will go know until i change the springs is 12psi. it has been 9.43@148 on pump gas and is a street car.
