translator pro vs B2B vs XFI vs BS3

[L8TRH8R]

Can someone tell me the difference in these products and what seems to work beat on a TR. I've heard so many different opinions on this and am ready to make an upgrade but before commiting to a system would like to know what users think.
Thanks.

B2B, XFI and BS3 are all standalone engine management systems. The Translator Pro piggybacks onto your stock ECM. They each have their own pluses and minuses. Post a little about your combination and maybe someone can help you make a decision.
