I have tried most of the VA type boxes, BD plug n play, raptor, and a few others that I have forgot what there names are.
If I was going to add a box for a certain power level and never want any more power I would choose the VA type box. To me they all seemed like very smooth running boxes and I liked the installation a little better.
I also have tryed most of the EZ type boxes, DD UFM, DD TTPM, and I think another one I can not remember. This was along time ago and I have tryed sooooo many that I can not remember all the names.
I choose the EDGE COMP box because I can adjust the power level for my towing situations and EGT"S.
Most all the fueling boxes incorperate a boost module feature, if not all of them.
Do like some one else said order all of them and them decide on the one you want to keep. Just make sure when you order that you ask them if you can return the box if it is not what you expected.
Useing whats listed in my signature I rarely have to tow above Level 1 which level 1 is the same HP as the none adjustable fueling boxes (within a few HP), remember I have stage 1 injectors which are the next step up in HP over the 275's.
