i just put an adjustable fp reg on my car and set that at 40 psi and bumped my timing to 14degrees. i run 93 octane and all but now when i get on itit sounds like something is is spewing in my motor or something some really weird sound. it idles really weird now it jumps around. i have a walboro 255 fp. and like the car jumps when im cruising at a steady speed. its a 92 5.0. im thinking its either the timing of fp or a vacuum leak.. does anyone have an idea??? thanx
