Nothing wrong with the remap figure, it's the torque you want to look out for and you have alot there. Each car seems to take differently, mine's about 255bhp but has about 299lb/ft and it runs really well along side my friend STi spec Impreza with 270bhp and approx 265lb/ft...he can't pass me that's for sure.
Do the N249 bypass, I tried that this weekend and I am really really impressed with it, the car is much more driveable, I feel alot more in control and the power gets down noticably quicker.
