mine was breaking up at about 5+ psi. Just installed the grantelli wires, grantelli coil, and ngk plugs gapped to .032-.038. and All I can say is OMFG. I thought my car was broke after I installed it. I thought I accidentally disconnected the wastgate vac line somehow, but nope. Car runs Amazing now. I also go the heat shield to protect the coil pack.thanks, i ordered grantelli wires and ngk iridium plugs last night. Gonna see how that goes. If that doesnt fix it next is my awesome MSD coil pack that was highly recommended :secret:. So i should probably go grantelli coil pack?
You should probably get rid of those iridiums for ngk 4306's.thanks, i ordered grantelli wires and ngk iridium plugs last night. Gonna see how that goes. If that doesnt fix it next is my awesome MSD coil pack that was highly recommended :secret:. So i should probably go grantelli coil pack?
