Dyno Tuned but still doesn't seem right

[Steve.In.Atlanta]

I have a customer with an s4r running dp header and mufflers and dp ecu with a modified file I made who's spark map is much like a std ecu spark map, but with dp fuelling.  no choppiness in the rpm range referenced initially here reported, I haven't ridden it personally.  has picked up maybe 20km per tank, which is sort of what you would expect with more adv.

My ECU was adjusted by the shop and think they may have mussed something up when they did it. The DucShop is going to drop in a programable ECU with the stock map on it to see if that fixes it. If it does, I'm going to send my ECU to be flashed and put back to stock. Any suggestions on who to send it to if that's the case?

i'm not sure what you mean by "put back to stock".  if you have a std ecu in the bike then you have a std ecu in it.

Sounds to me like they mapped it for power or optimum A/F ratio and not driveability.

yes i agree.. drivability means  tuning all the transitions , low speed and midrange especially between 1500-3500rpm this take a lot of time and most dyno boys wont do it ,,the off throttle fuelling needs 1-2% added as well at the lower end to smooth things out
