We first saw this 2012 Kawasaki ZZR1400, back in 2014 when a previous owner booked it in to have the ecu re-mapped.

At that time the only changes that had been made was the standard air filter had been swapped for a BMC, but the exhausts remained standard. (Original graph attached)

Now the new owner purchased it fitted with GPR exhausts and because he had his other bikes re-mapped here, he knew that this one was not running as good as it could.

It was put back on the dyno to have the fuelling altered to suit the new end cans and as you can see from the latest graph (which should read GPR exhausts) it has gained a few more horses!
