Every person except GTLAW (GSXR750 too) must be wrong. Somehow all the empirical evidence we have gathered is wrong too. We are all doomed. The minimum whp expected is 10whp on a modded car, and more as a first mod. The stock intakes are good, but CAI's will create more power, and more than the 4-6 you claim. We should just spam this thread with dyno results.
Bottom line is stock, second line is full exhaust, 3rd line is CAI and pulleys. Looks like my low end has dramatically improved as well. The dyno must be lying.
