I have maxed out the 20G's wastegate at 25-26PSI with no problem other than snapping an axle...they have a new WGA..but I dont have it yet..$175 and I have been poor after axle snap then $200 tow truck ride then DSS (Drive Shaft Shop) axles put in
I will push 30PSI on this kit once I get the new WGA that I promise. If you get a new kit ask for the stronger WGA because you can change springs depending on your power level...then you wont be stuck like me
