I have a keydriver chip and i used to run 15 psi on mys tock fuel and it would hit 5500 and it would stutter out.. but i put a 255 fuel pump and a fuel regulator and i ran it at 15psi with all the fuel up to 45 psi and it did the same thing. the car started stuttering is it the key driver chip or is it something else. cause something is going weird..
