Should I have bought a Bullydog/BMP instead of PCV?

I joined this forum after I bought my RZR and a PCV. Now i’m worried I bought the wrong tuner. 🙁
I want to lock my throttle and open up my TB 100%. Can this be done with my PCV? I know it can do timing, but I haven’t been dyno’d since that’s the only engine mod. I have a stock map from their site. Can I at least get 100% from this thing if I get it dyno’d? or is that a waste of my money and I should just sell it and switch to a bd/bmp combo? How about the seat belt sensor? Can I turn that on/off with PCV?
If I can’t get the most out of my machine with it, then PCV will be in the classifieds:)
Thanks!
