If you want to push a little more out of your Stage 3 Turbo Upgrade, look into the AGP Stage 3 WGA. This replaces the factory installed piece, and will allow you to hold higher boost pressures to redline. Other benefits include reducing the amount of boost spike, as well as eliminating the oscillation that is common with light spring actuators. This kit includes a custom machined bracket to mount up to the factory points on the back of the compressor housing and is fully adjustable for preload.
This is for the Mopar Stage 3 Turbo.
