Any news on the GTI upgrade?
what do you get with the upgrade?

if i have a pooty bolt, does this affect the upgrade?

the new gti valve accepts the pooty mod spring. so your bolt will not affect it, you can still use the spring and bolt. you would be installing the new valve, grips, screen, board, pressure sensor and solenoid manifold / solenoid if its changed.
