I went from 254whp to 306whp
All I did was get bigger injectors, intank fuel pump (got rid of inline fuel pump and vortch FMU) I was able to turn my boost up from 5psi to a safe 10psi with the s200b Hondata. I would recommend Hondata to anyone and everyone. Before you go jumping into a hondata I would read that link Tony posted for you. This is not something to just put on and go with it. It'll take some time on a dyno and good tuning to really get the max effects of it.
