I recently bought a 2015 Mustang ecoboost (50th Anniversary) and it already had a IWG75 installed in the car. Right now I have the check engine light on and diagnosis says "Overboost Condition", so because of the wastegate.
I was thinking about to add the burgertuning JB4 initially...
I have the Turbosmart IWG-75 now with a 7psi spring. Looking to move up to a 10psi spring, either by replacing mine with a 10psi or acquiring a 3psi spring to add to the IWG.
Anyone have springs for sale?
