As you all know I have the profec B boost controller. Well, I had it for 2 days before it just stopped working. WTF..some quality!! Anyways, have any of you seen or use the HKS boost controller...either of them?? The EVC IV is a bit too much for me at $539 but is the EVC EZ as good as the profec b is?? does it have the same easy to use features?? Let me know if any has used the HKS or if anyone recommends it over the profec b which was a GREAT BC for a day. blah...

I haven't had any exp. with their EVC EZ boost controller, but you get what you pay for when it comes to HKS, IMO they make high quality products. I'm sure someone can give you some first hand advice. If you bought the profec B new, try calling Greddy and asking for a new unit, or see if some vacuum lines came off.
