made 4 rwkw more with the butterflies operational rather than tied off with a ziptie under 3800rpm

As it has been said, there are many variables involved - FWIW, mine are being controlled by the ECU...power curve shows a minor dip when they actuate, but has nearly been 'tuned out' - the low load everyday-driving makes low-end torque worth keeping IMHO.
