When an EVC is installed, these solenoids are removed from the pathway. The stock wastegate springs, set at 6 psi, are the only things controlling the boost as a fail safe. Vent any vacuum from getting to the wastegate actuators. Stock design has a set of boost cut solenoids in the vacuum pathway to Longer, but vacuum is still a function of the system. The amount of vacuum is restricted slightly, keeping the wastegates closed The amount of vacuum is a function of the entire system. The wastegates are controlled by a pair of actuators that moveĭepending on the amount of vacuum pressure applied to them. Open, they allow an alternate path for air to move through, allowing boost When they areĬlosed, the turbo is the only pathway for air to follow. Wastegates control the amount of boost turbos create. Also larger injectors are needed (555 cc or bigger) If youĮxpect to run more than 12 PSI an upgraded ECU is a must! The remappedĮCU is critical to keep proper air/fuel ratios at higher boost levels the Steady low boost levels) requires and electronic boost control. However, to run higher boost levels (or to run more Boost jets are goodįor about 12.5-15 psi. HP on TTs is getting a Jim Wolf ECU and 'boost jets'. Here are some pictures I am trying to see if I can get a company to custom make a boost gauge and wideband to see if it can fit on our air vents.Apex'i Super AVC-R Boost Controller Installation Typically, the first step in increasing boost to gain more If you choose to have the gauge lights dim when you turn your lights, buy tap a fuse from Pep Boys, from the fuse box at the very bottom, there is a fuse for Illumination pull that and plug in the tap fuse connection with 2 fuse so that will make you gauge lights dim. If you have the Illuminated door sills, then you can take power off the extra wires from that main connector for the door sills.įor Constant 12+ need to tap into the Red wire, for Ignition power tap into the White wire and for the ground tap into the black wire. The overall takes about 2 hours because on the drive it's near impossible to find an open to fish the vacuum lines inside the cabin, so I had to use the right side next to the cabin filter far left there is rubber boot you can make a small hole and fish the hose inside that area. Hey Guys I finally did the installed on the boost gauge, I try to seek a gauge out that look like it came from oem but it may look like rice to some taste however I can now see what boost I make in certain ways when I step on the gas.
