fuel intenseifier and itp's regulated return

[2003powerstroke16]

what are these mods and what kind of power can you get out of them???

[DoubleDpsd]

they provide more fuel, more often, more efficiently. I did not notice any power gain. It is a supporting mod.

You'll maintain FP on the top end, which does keep the power more stable. However, peak power won't be significantly changed. With larger injectors, an upgraded lift pump and regulated return is a necessity.
