I suspect most tuners could do this.
I got my Upsolute map changed along those lines.
Personally, if I were looking at another remap, I'd be seriously considering one from Bell Auto Services, read quite a few good
reviews of his service on here, and I gather he'll write the map to do exactly what you want. All for a good price too.
You will notice the lack of urge around the affected rev range, although it'll still be quicker than standard. Mine is limited between 2-3000rpm, then I can feel it really pick up in the low 3000's. I find it a little frustrating, but it was my choice to do this rather than fork out for a better clutch.
I take it you've bought a barge too then
