having trouble deciding which one to get. the avc-r would match my apex afc but the greddy is about $150 cheaper. just wanted to some opions on what performes better, looks aren't really important sense niether look bad.

 

I went with the greddy one because its simple and I've heard it worked great. I have no problems with it. The avc-r has ALOT of features though, but none of them I found I would really use. Main reason I went with the profec was because I couldn't fit the s-afc, my turbo timer and the avc-r along with a stereo. Both are good though.

 

Profec B

 

I prefer the Profec because it has a (more reliable) dual solenoid.

And, its just simple and easy to use.

The ACV-R has so many features and gizmos that I won't ever need. Plus, you need to scroll through menus to switch between boost settings.

On the B, you just press a little button.

Both are awesome, but the ACV-R is just more flash.
