A friend of mine suggested that we pinch one of the hoses, I think 
for the WGFV, to up the boost for fun.  I declined on the offer, 
thinking if it was that easy, there wouldn't be a market for chips.

What are the effects of doing this type of thing?  Does it equate to 
bleeding off pressure from the hose going to the ECU, making it not 
see the actual boost?  Or, what?  I'm not yet at the point where 
things are all making perfect sense.

I was thinking, ever since someone mentioned that it takes load 
and not rpm's to build boost (which is evident just from driving), that 
I would probably learn alot from that Corky Bell book.  I'll have to 
get one of those.

Thanks,

Ken
