I was always under the impression that dyno runs were best done in 4th gear as it gave the best spread of power, that could be your problem. my bluefin stage 1 gave me 241bhp, 249Ibft on a well renowned rolling road, and i have seen other with similar results.
Also bluefin remaps require a small time period to bed in for the ecu to adapt completely.
Believe me adaption will give you extra 5 ps, sometime you even might loose power. I have tested this also. Also standard was done withoud adaption, so if you would add 5-10ps to it. Then sc remap is giving you around what, +10 HP
What golf are you runing? K03? K04? Mine is K04. Seeing 241 ps with k04 car is ridiculous :D
Problem is not the gear. Problem is the map, try vagcom datalogging and check for your self what boost their remap is specifying at high rpms.... It is very close to stock, that is why they do not have power over there.
