i recently installed the greddy profec e-01 ....and my friend helped me with the the tuning i think it was 14.0 or 16.0 psi and when i was drove it sometime after, i felt the boost kick in at 3000 rpms but it kept jerking as if the trottle was being pressed repeatedly. Is this what they call boost spiking...also i think this setting is set on auto so i've already tried lowering the boost but it doesn't change a thing....
