Cool idea and I can appreciate the ingenuity. But I don't think it's worth the effort on an otherwise stock engine. I'm not doubting the power increases, but where in the RPM range? If the intake air goes through one tube with the MAF sensor then splits into two tubes to feed each TB, then it's NOT getting 100% more air. It IS getting a more balanced air charge at the least. I believe it would benefit from two individual intake tubes with two separate MAFs and tuned accordingly or no MAFs and converted to a speed density tune. Of course, then placed onto a big-cube or high-winding engine.
