I have picked out 2 from the Rx7 store in the $300 range. One is the Greddy Profec B spec-2, and the other is the Blitz Dual DSBC spec-s. The Blitz seems to have more features....but I know nothing about boost controllers. If anyone knows anything about these I could use some help.

 

my personal opinion is go with the greddy. Their electronics seem to be top notch i have never had a problem with them. They are decent priced and they get the job done

 

I heard you cant go wrong with the Greedy Profec B Spec 2. The quality as well as the simplicity of use is very good. Then again this is what I have heard. And also people I know who have this boost controller in there Turbo 2 like it alot.

 

I used to run a Greddy Profec-B in my RX. Excellent boost controller, installation and use is easy and to-the-point. Switching between low & high boost settings can be done with a push of the button on the unit, or an optional remote button you can attach to your steering wheel. Only reason it's not in my RX anymore, I wanted something with more features and bought an A'pexi AVC-R. The Greddy is now in my turbo'd Miata.
