Turbo Parts & Kits - Billet Wastegate Actuator

There are three main things that primarily control the boost on your 1.4T.  The ECM, the bypass solenoid, and finally the wastegate diaphragm. This is the part that holds the wastegate flapper closed until desired boost is achieved, then it releases exhaust into your o2 housing/downpipe to maintain that desired boost.  The factory one is known to fail and is also known to not be able to hold desired boost to redline.  This is an aftermarket replacement bypass valve that has increased spring pressure which will hit your desired boost quicker and maintain a more consistent boost for higher RPM power (due to keeping boost PSI higher to redline).  

Important: This product will help avoid a P0299 "under boost" code, but will also increase your chance of getting a P0234 "over boost" code.  Depending on how your car is tuned, this will most likely require a PCM file update.

Great product!!!

Super easy 10 minute install. My sonic holds boost all the way through to red line and kept getting boost after every shift. I have my preload set to 1 1/2, but I’m also in the middle of a tune. I recommend this.

Product works well, but my preload only needed to be 1 turn instead of 3. Overall holds boost well, I have trifecta tune, not hp tuners. I don’t know if that’s why I was getting an overboost code.

Good value

I bought this cus I was lacking power and it could still build boost just not as much bought this and was so excited I followed the video on YouTube to preload the actuator. However since I can’t tune it right now I had to work around the over boost and under post codes which this de it’ll will give the car. So I found the sweet spot after that I have this weird mechanical sound after I let off the throttle at higher rpm so probably just needs a tune but seems to run fine right now.

Zzp waste gate

It’s a nice product. However the pre load video provided did not set the wastegate correctly. I had to set it to only one half turn. Also The car prob needs to be tuned for it since it will occasionally throw an engine light on high revs and reduce boost. Can definitely feel it hold boost better throughout rpm ranges over stock.
