Hmmm. Well in the process of my alarm installation we've found my car used to have a boost controller, turbo timer and some sort of temp gauge. Also my standard boost restrictor has been removed.
Now with that removed and a catback exhaust my installer seems to think I'd be running atleast 14psi and he says I'm risking detonation because my timing or something might not be right and that I should hook up a boost gauge to know exactly how much psi I'm running and he can make it so I don't run the risk of detonation.
Is he talking shit or should I be concerned?
