I have a question I have a cobb ap2.0 and was wondering which would be better..Looking at two Ebc's the grimmspeed boost solenoid or the perrin ebc pro? And Can or should I run a manual boost controller a friend of mine said I could but I don't think I should he suggested the apexi ebc??? Any Help or suggestions???

 

I got the grimmspeed one and i love it. it makes sure i hit 20 psi each gear. dunno anything about the perrin one though.

 

i have grimmspeed one, so far so good, i am running 27 PSI no problem, as far as boost controller, if u have an accessport u can control ur boost with it and no need to spend money on one, but if u decided to buy a boost controller then no need to buy a boost selenoid, cuz the boost cotroller comes with one that is suited for it

 

I have run both the Perrin, GrimmSpeed, and a generic MAC valve. The Perrin was underperforming for what they charge, and I felt it was not accurate enough for my liking. The generic MAC worked better than the Perrin, and was more consistent. Currently, I run a GS ebcs. Essentially, it is a custom ported MAC, with an upgraded and precision valve installed by GrimmSpeed. It is certainly worth the money, and with any GS part you pay for performance and quality.

 

Thanks for the help....
