I had my 2001 GSXR 1000 mapped on friday morning at Clifford Cycles in Omaha NE. It has a M4 sport high mount full system, K&N, and PC IIIR. I loaded the m4 full system map before going there.
The basline run was 138.2 whp and 71.7 wtq (SAE)
After it was mapped it laid down 142.2 whp and 74.5 wtq. It has gains of 4-5hp from 6-12.5k and 2.8-3.6k, and from 4-6k of 1 to 3hp. The throttle response is much better and the bike feels much smoother and snappier. The same dyno recently laid down 107whp for an 05 zx6rr (mapped pc3, Arata full system) and 94whp on the same stock bike, so it's not very generous in terms of numbers. They said the newer (03-04 gsxr 1k's) put out 140-150whp on their dyno depending what's done to them and the luck of the draw (getting a good one).

My 01 with just a D&D Slip and a tune made 143 whp SAE. However this is done on a 248 dynojet where the rollers have been split.

I personally dyno'd my 01 1000 at my work and it put down 142hp with the wrong map in the pcIIIr, I talked to a buddy of mine that runs a performance shop and he said he would tweak my map a little and easily get that bitch puttin out 150.
