Redtop SR boost issues
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? |

Make sure Vacuum port you selected isnt clogged (one of the ports on the T/B doesnt really work)
OR Waste Gate Diaphram is torn. Test it Per FSM
