RE has good tech support/customer service, call them up or email them and tell them what you want it to do, I'm sure they can help you out. According to WinISD I believe the peak output comes at about 2hz over the tuning frequency of the box. If you are making it a daily driver though I would tune it a lil lower than 36hz, probably more like 28-30, I believe thats what RE recommends on the site.
