Is there really a difference on brand of boost controler? Im curious because my tuner recommended a COBB EBCS. Everyone I know recommend a Grimspeed. And I managed to get a free Perrin EBCS.

I know they all have the same job controlling boost more precisely but is there really a variation?

 

I would say some brands are just better and more reliable then others

 

i'm sure you're safe with all 3 brands. Free one is always better

 

I hear ya. It was kinda of a stupid question just dident know if there was a HUGE differance
