My Perrin 3 port just failed. What is the best known 3 port to go with for a replacement? Should I go Perrin again or should I go another brand? I want to order asap let me know what you guys think! Thanks.

 

my grimmspeed has been reliable for me for like 5 years now.

 

GM is still the best, and cheapest.

 

I ended up ordering another Perrin 3 port boost solonoid.. they no longer sell the version I currently have.. they only sell the "EBCS PRO".. it's an updated version that responds quicker and has a better anti-corrosion on it.. I ordered it from STM at 3:00pm on Wednesday.. and it was on my doorstep the following day at noon.. I installed it Thursday afternoon and my car feels like an absolute beast again... it's amazing how much more power I feel... the solonoid on my old Perrin EBCS was shot..

Just ordered another set of spark plugs and going for a re-tune at CBRD in may... can't wait!

 

Since you changed the solenoid, you should make sure you're not overboosting.
