Which spring for Forge MBC
I'll be going for my tune in two weeks, and I was wondering which spring I should have installed in the Forge MBC for best performance.
Right now I'm boosting fine, peaking at about 20 psi with the softer spring that comes pre-installed in the controller, but since I'm sure the boost will be turned up when the car is tuned, should I swap in the stiffer one?
Or should I just bring the stiffer spring with me and let the tuner decide which is best to use?
Thanks for the help guys, and mods are in my profile for those wondering.
