I don't have easy access to a dyno, so I can't say what the HP was before or after. But very unscientifically, I can say the difference is huge.

Running homemade BD, the increase in MPG will take me about 6 years to recoup the investment, but someone running $4.00 D2 might recoup in a year or two.

The fun factor alone made it worth my investment.
