I have been down that road on many of they engines I dyno for other people. The O2 and EGT's can lead you down the wrong road many times. Always tune for best HP. I look more at the BSF # more than anything and have found that the merge collectors straighten out the fuel curve and increase torque more than a peak HP increase. That being said your power #'s are more useable and consistant through the curve.Happy Tuning and Happy New Year.
