It it normal for the power band to only be 5200rpm to 6300rpm, the rest seems fairly slow then a lot of power in this rpm range

have you recently put in a new timing belt? Is it possible that your cam timing is off one tooth? A cam timing change will move your power band

Should be loads of power all through rev range if std.

should feel a surge at 3500rpm and should push you in seat hardest at 4500rpm and slowly taper off to cutout at 6400rpm ish. you dont feel power you feel the torque as thats what gives acceleration.

Also toblerone (pointy/spiky) cams are usually low duration. if the nose of the cam is big radius its a big duration cam
