If you're getting 40' ranges out of a LS, then I have no idea what you did to it. Whatever it was, I wouldn't be bitching to people about their supposed 100' ranges, because it looks like you don't know jack about modifying LSes. If you're getting 40' ranges with a LS then you need to stop ripping on people and actually go do something better to your LS. Yeah, maybe he didn't get 100' ranges, but I'd bet my soul he got more than 40'.
If you had read the post you would've understood those crappy ranges: it's incredibly leaky! I dropped at a friends house and it consequently fell down 2 flights of stairs and it cracked the plunger tube thingy Yeah, it's a fail but i've started a new project on a Ls and it should prove to turn out better.
