Anything you don't understand ask Scotty!
You can check out morepowerracing in the states as well. They have some good deals on Power Commanders at the moment. Think they are about $260.00 us plus freight. You will get good and bad reviews about them but I have one on my 06 Softail with heavy breather, big radius pipes and se 211 cams and have had no problems.
My 2 cents worth.
The TTS seems to be the most versatile and best bang for buck and it works. If you know any thing about computers you can do it yourself. The TTS will also follow you on your journey for future modifications, Cams, Pistons and barrels down the track.
Match up the mods and tune, and all is worth it. I pulled the packet out from under my seat and put some more padding in there and that made huge difference. The pillion seat got pumped up a few inches, much better.
Enjoy
Hafta agree with you MJ. Maybe not "rubbish" but certainly overpriced.
I read on the net "somewhere" that V&H didn't even rate in the top 15 performance pipes in the US. I was researching while looking for pipes. Bought Hookers myself. .
In the top 5 were BUB, D&D and supertrapp amongst others. Hooker were in the top 10.
V&H do look good though.
Just my opinion
