boost controllers

whats better:
HKS evc5
or
Greddy profec-e01

greddy one

Hi buddy.
I own an S15. I have Greddy Profec-B Spec-II boost controller and its easy to use .
You dont need Profec-01 which is a linkage to other Greddy products. EVC Basic and Pro are excellent as well but EVC-Pro is more advanced for circuit. Both Greddy and HKS boost controllers have scramble boost, peak and warning modes with sound and red light display,and good response. I reccomend HKS EVC Pro though.

i know i;m reviving a dead thread, but i rather post it here than create a new thread

out these three which would be better or are they roughly the same

APEXi AVC-R, Greddy Profec B specII, BLitz SBC-iD

:rofl:























:worshippy:

Don't laugh. It really works pretty well.

:eek:

Hey I just got the Greddy Profec B-spec 2 i wanted to know if any one knows how I should set the "Gain" and the "Start Boost" I have a sr20det and I want to be around 15psi. When I set the controller it will go up to 15 but then drops off??? Or will not go all the way up to 15, or will just go past it and then back down??? I can't get it right let me know if you can help?
Thanks
Matt
