i was wondering if anyone could tell me which one is best for our applications? ive been looking into both an im thinkin teh apexi is but i just wanted toget your guys opinions as well.

 

i have never seen someone using the hks one

 

Well like said above.

The SAFCV is more widely used so you will have a broader knowledge base to work with.

 

the hks is much cheaper...and works great..I had one for a little while..howver...you will have to get the car dyno tuned with either or it will be just a best guess tune....you might not need one in any case..what mods do you have?

 

Seems like the SAFC is the one to choose.
