That is one thing I noticed is that I seemed to lose a substantial amount of torque with the BCT's.

I'm surprised you say significant. Are you running a stage 1 with download or SERT? Is it possible your bike was not properly tuned in the first place?

I put the BCT baffles in my SEII a couple of weeks ago and had to adjust the VE tables to reduce the decel popping, which I had tuned out with the stock SEII baffles. I really can't feel any difference in torque.

I have a carb rather than fuel injection. I could easily tell the difference in the power. Tuning had nothing to do with it as I had tuned the carb both to the V&H baffles and also to the BCT baffles. I wasn't able to get the power with the BCT baffles that I could with the Quiet baffles. I can only attribute that to the amount of back pressure or lack of it. I am thinking that I should have dynoed both before and after the installation and removal of the BCT baffles.

If you install them, I hope you have better luck. Maybe the fuel injection will make a difference.
