I also have the cobb ap and Wasnt sure which 3port to buy. Gs3port has been proven to work and has been in the market for a while now. Knowing the Gs3port work with the Cobb maps is a relief. Ill most likely get Cobb to be in the safe side.

 

Same design and function, both are Mac. The ecu wouldn't be able to tell the difference.

 

Our valves has a slightly larger orifist. It is also heat treated. I am not sure what the difference is between ours and Grimmspeed, but from all the logs that I have seen, there is no consistency. Some will over boost and some will under boost.

Good to know probably just go with cbcs

 

i bought this and guess what, they sent me a cbcs for a subaru. first, they didn't send a bracket with it. then, they sent me a bracket but it's a wrong one. then, when they finally sent the right bracket i couldn't install it cause the socket won't fit the socket on my evo. turns out, they sent me the wrong piece after all, it's for a f***ing subaru! sorry for the rant, i'm just so disappointed with cobb.
