Forge 'Splitter' BPV installed. The reason why I chose this model was because it can be used as a BOV, as a BPV, or as a hybrid of the two with a small percentage of the air being blown off.
Anyway, it took me longer to pull the car around to the garage at work then it did to install. The adjustable spring tension is easy to set and I ended up about half way to the maximum setting.
The increased boost hold is noticeable over the 93k mile stocker with higher peak pressures than before.
