Since the ECU remap the kick in the lower rev range is definitely noticeable, maybe its just a coincidence that there is a noticeable improvement on my bike in the area where the exup operates, although i think not. I have the benefit of riding the FZ before and after the remap with the exup in operation on both counts. I'll be keeping my cables attached. I don't wish to start yet another debate on the exup as its been done to death over the years, i just want the OP to be aware of the different experiences we've, with my personal advice being to retain the exup and if possible, get the ECU remap.
Couple points here fella - no. 1 is that this region of the revs is one at which emissions readings are taken, so the bike is flattened off here - lot of modern bikes have a problem with a flat spot at this area of the revs. That's why you'll be feeling the kick up the ass so much at these revs, remapping it here makes the biggest difference as compared to the original power if you get me.
Your tuner is right on the older Exup valves - they were to help boost low end performance. From everything I've read though the newer valves are just noise reducing.
