I just wanted to let everyone know about the good experience I just had with HPA. John took about an hour out of his day to help me pick a converter. (3000 Stall with 2.5 STR) If their product is as good as their customer service I'm sure I'll be happy!
I also told him I heard about them on this site. He mentioned that he is going to become a sponser as soon as he gets time.
Thanks all!
