explain your thoughts on the bypass valve. I don't see how an upgraded one would be of any beneficial performance increase. It is just used to increase fuel economy basically.svtfocus said:Yes, CPU upgrade, s/c pulley, exhaust, and I'm thinking bypass valve would be good too. The stock ones look cheap and unreliable. I have a feeling this upgrade will be coming up soon as a priority. But, there are no upgrades yet (that i know of), so we just have to be patient, and let the genius gearheads hook us up!
It is to a small extent. The pull and plug mod has been proven to be false. I have found that stock the bypass only leaches a small amount of boost within the last 300-400 rpms. To make 14 psi you need a smaller pulley. The bypass becomes and issue slightly with a smaller pulley as it will open, again at the end of the rpm range, but the car will make 14 psi for a significant enough ammount of time.CoBIZZLE said:The bypass valve is also limiting boost to 12psi. There are plenty of RL owners that have pulled and plugged theirs and are seeing around 14.5psi.
