Redtop SR boost issues - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

For awhile, I wondered why my boost levels would shoot up past 1bar depending on how much throttle I give even when I had no boost controller installed. It wasn't until a few days that I finally had the time to pop the hood and take a look around. To my dismay, pretty much all of my vacuum lines were cracked and/or ripped at the openings. For some reason there was also a line going to the EGR system (which I've bypassed now).

So..

EGR's removed
Vacuum lines have all been replaced

Why am I still overboosting?
