Hello guys. I just wanted to ask you 3sgte gurus or what is considered a good zone for our cars. I was asking my brother and cousin and they said usually you don't want to go any higher than 12.5. Just wanted to know where I can be. If needed this is where I am at with motor wise. I have a st205 swapped into a st165. Full 3" exhaust, upgraded inter cooler core/pump and On its way are ARP head studs.Thank You.
