If it's pure burpy numbers you want then build for 66hz. If you peak at 33hz you'll also peak at 66hz.

Don't tune the box to your peak. Tune it a few hz below the peak, once you get it in the car the combined setup will peak a bit higher than the tuning.

You need a bigger box and more port. Try to get 10 cubes after displacement with 180-200 square inches of port if it's purely for burping. Or 6 6" aeroports across the back of the box.
