Hey guys I am new to the forums here. I've been owning an Fr-s for a year now and will soon be turbocharging it with sbd kit using the oft. However, I was wondering if I turn up the boost from the base (10 psi) to let's say 14psi, will I need a retune? I will install turbo kit in about a month from now. I asked shiv but obviously he's a busy man and all. Thanks in advance for help
