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.

Holds boost

Holds your boost into higher revs. Works great. Excellent quality over the stock one. Easy to set and install with the turbo still in the car. Fast shipping to Northern Canada only took 5 business days! Will definitely be buying more products from ZZP. Plus they give you a zzp sticker with your first order:). You'll need a tune to run this. I ran it without one for about 30 minutes and it gave an over boost code. Had to swap back to stock till i got my tune. overall great experience.

Overall decent

The installation was pretty simple, one man job, the materials it’s made of are great quality you can tell right off the bat way better than oem, but I really felt no difference, maybe a little bit
