I need help finding a new boost controller. Towards the end of the summer i got rid of the E-manage (blue) and went with the Interceptor-X. Because i was using an emanage i had a e01 to control the boost and do programming to the emanage. well the e01 is a big item *IMO* to have JUST to control boost, so i was wondering, what are you other turbo guys using for boost controllers

I know some are using the Greddy Profec b Spec II with good results.. on the Rx-8 and other FI'ed cars.

I had the Profec B Spec 2 and didn't have any issues, but I have heard others that have. I think a lot of people would recommend a manual boost controller, or a HKS unit.

i'm using moostafa's profec b 2 for the last 9,000 miles, it works perfectly fine, no issues here.

i can't say if it's better or worse than anything else out there, since it's the only one i've ever used.

i also been looking at the greddy profec b but was thinking about the apexi avc-r.also i i believe super street mag rated hks evc 6 as the best boost controller.
