Yes that is what I understand happens from two owner feedbacks. It appears the valve opens around 3200 which is why one owner feels there is more toque lower down. I dont believe peak toruqe has increased but i suspect by opening that valve lower it has a flatter torque curve lower down. You remember the dip in teh chart around 3200-4000 well if what is said is indeed true I would suggest (speculation) that opening the pipes straight through has removed that somewhat and mate the curve more regular. Its a software change only and teh PKF has also been changed to accommodate the adjustment one imagines along with some new thottle mapping. Good news and was probably a tweak which was waiting in the wings.

This was also reported by Apollo on Pistonheads.
