Like Mr. Hannum said, "A sucker is born every minute." Both of these products are cheap work band aids to doing the real fix, a re-map. The BP was actually the third item in the snake oil line for Triumphs. The first was sold as FRK, again developed for what ---- BMW's and then used on Triumphs. The guy claimed it had a CPU in it. We had several electrical engineers on that forum who not only caught the FRK developer in a bunch of lies but came up with phase two, a DIY item called DOCTR. Then came BP. Again, the principal behind all of these items is to put a new temperature curve on the air temp sensor to fool the ECU. Anyone who deals with ECU maps will tell you that playing with one sensor is not the way to fly. Although it works for some, the real solution in the Tiger world was the ability to get a free program called TuneECU where they could remap the ECU, change ignition timing and A/R ratio's across the RPM spectrum. BMW's aren't that lucky. Power Commanders and similar boxes are only solutions. Go do some research and find out how the stuff works.
