I have sent my first ECU for my 2014 Ninja 1000 (I think it is called Z1000 SX in NZ) to Ivan's Performance for a flash. I had just put a full Akrapovic header on the bike and removed the smog. I can say I was quite pleased. The is not much to be had on the Ninja 1000 with a header or tune. Ivan's shows three additional HP and two additional torque. The stock engine gives up at 10,500 rpm and with the flash it now pulls to 11,500. The biggest change is the ridability after the flash. Most tuners use the Woolrich software to flash the computer and it cannot remove the fuel cut upon deceleration. The bike is extremely smooth and I couldn't be happier. I confirmed the bike was not too lean by pulling the plugs after a few hundred miles and they do not show lean condition signs.
I recently bought a 2012 ZX10R that had an Archer tune for an Akra pipe, smog removed and a jumper plug for the smog sensor. The bike came to me no longer having the Akra pipe on it, but I already had one. The first thing I did was put the Akra pipe on the bike and take it out. I was not happy with either the power or ridability of the tune. I pulled the ECU and sent it to Ivan's for a re-flash. Ivan's requires a PC-V in addition to the flash as the flash itself just cannot get close enough, saying it would be too lean without the PC-V. He supplied the flash for my PC-V, which I also installed. Archer did not require a PC-V. I am again extremely happy with the tune. Tons more power than the Archer tune and much more ridable. I took the ZX10R to a friend that had a dyno and he tested it. He said he could "tweek" a few things but he was impressed with the tune overall. Not lean at all. FWIW, Archer now works for Woolrich and no longer offers tunes.
I hope this helps.
