planning a few mods..., good ideas/ bad ideas Options

[Redline08]

So im lookin to squeeze as much power out of my daily driver as i can without molesting it with turbo or nitrous. Heres what i was thinking:

-Headerback 2.5" exhaust
-Accord CAI
-Fuel pressure regulator? (Still dont really know what they do...)
-SAFCII
-GT-Four fuel pump

What do you guys think, worth it? and what gains to expect?

I have an auto and i was also wondering if the SAFCII is effective with autos, I was hopeing it would get the most out of the intake and exhaust but i noticed it can change shift points or something, might save the problem of bogging down terribley in the bottom of second.

Thanks guys I appreciate it!
