I actually read this whole thread under the assumption that it was about modding your car for free. I guess it's more about aruguing over cold air and cutting up airboxes. oh well.
Anyway, my idea for a "free" mod is this, and take it easy on me, cause I'm not 100% sure about the details. The computer reads boost from somewhere and there has to be a hose running to a sensor. if you put a t fitting in this hose with a really tiny hole in it, you should be able to bleed off enough air to up the boost safely to maybe 18-20 psi. I've heard people say each pound of boost is worth about 6 hp, so we're talking like 18-30 hp. that would be nice since a T fitting is only around $3.00 at home depot. I'm going to research more and try this mod out (now that I have a boost gauge installed) and make a full report. once I know sizes, (ie hole diameters for the sides of the T and the vent hole) you shouldn't even need a boost gauge to do this mod (even though in my opinion you'd be crazy not to know what exact boost pressure you're running).
Anyway, I'll dish when I get the info.
