I just put on my Van Aaken box and took off the EZ just to compare the two and what has been said on this forum is pretty much what my SOP meter tells me. The EZ on 3 is about the same with maybe little more at really high revs but not quite as much down low. I definetely can tell it idles much smoother with the Van Aaken maybe even little smoother than stock but the EZ made my truck lope at idle when cold and surge little bit while cruising. I liked the EZ and think it may be little faster on 4 but for the smoothness of the Van Aaken I believe this is the one I will stick with on my truck. I wish I could keep both long enough to tow with both back to back and had my guages installed to compare more in depth but I will not keep the EZ long enough for that test. Any one have dyno runs of these two boxes on same truck and dyno, would be really interested to see the results?

 

This leaves me open to some abuse but, what is a SOP meter. seat of pants?
