Hey mate,
Sometimes the point of being mapped is not about being able to get more BHP out of it, or improve torque. But to simply get the bike running smoothly with the add ons that you have purchased. Most bikes are bought with Off the Shelf fuel maps in the ECU and so the bike does its own intelligent fuelling. However as we all know one bike can be very different to another, even though they may be identical.
I have both a ZX6RR and 2006 ZX10 and both have been mapped and think it was well worth while. My mods on my 10r were quiet dramatic (cans, air filter, gipro with atre, decat and pcIII) so it was worth the money. Steve at Motrac spent hours just trying to get the fuelling sorted in low revs. He said thats a common trait with Kawasakis, that the fuel map is pants.
Often a remap to the average rider, with limited mods, won't seem that different but if you were to compare the graphs on the dyno before and after you will see differences. it just whether or not these translate to you in the seat.
If you think you've been ripped off, then go and speak to the guy again or go elsewhere and get a second opinion. However you likely to have to pay for any dyno work, and then its up to you to try and get the money back of the other guy.
The Dyno equipment can also make a difference on output so again, going elsewhere may not prove conclusive.
