Any noticeable gains when running a high hp tune and a ficm tune? What ficm tune works best with high hp tunes?

I believe Bill stated that the FICM tune will help the High HP ECM tunes but wont be as noticable unless you have injectors. There is only so much you can get out of the stock sticks. The FICM tunes are suposed help bring on the power on the bottom end.

He has posts on it on both PSN ans PSA, and other sites aswell. You probably already read those though.
