Installed the Greddy Type LS intercooler mostly without a hitch, then drove for the first time and realized I had no control over boost levels because I mucked up the vacuum line wiring. Translating the directions and using their terrible grainy pics, my routing and solution can be found below at the video:
Does this look right or should I have gone a different direction?
As it sits now, car is perfectly drivable and usable, lots more boost control operates as normal...until you are at 4k RPM and half throttle at which point the boost gauge will quickly max out. No other mods besides the intake, a catback exhaust, and the GFB BOV. in the places where it used to pull .65 BAR at 4k RPM and full throttle , it's now able to max 1 bar in the same condition. It's all very very normal until that threshold of RPM when the VCT timing advances .
SO, either a vacuum issue with my wiring not controlling the boost solenoid or wastegate correctly? Or possibly a FAILED wastegate actuator? Where it just cannot operate as designed anymore given the extra air flow from the mods and suffers deadly boost creep as a result .
Any thoughts are most welcome, thank you
