I just recieved my RR 2.75 no-slip pulley today from Amazon racing. The question I have is why #1..is my car making 2lbs less boost compared to my 2.8 pulley? Could it have been packaged wrong? and the next question I have is when I get on it, it slips worse than the other pulley I had and this one has a tighter belt?

Doesn't make sense. What belt are you running? Gatorback may be getting torn up. UMMMM?

Im running a gates belt. It is pretty tight, so the oonly thing I can think of is that it may have been packaged wrong. Even with the belt as tight as it is,I still dont understand why it is slipping SO much:confused:

JMHO, but I think that if you go with too small a pulley, eventually you end up with such a short gripping surface that a tight belt just won't do the trick anymore. Also, I don't see idlers in your sig. Do you have bigger idlers, to wrap the belt around the pylley a little bit? Maybe you see 2 lbs less boost, because of the slipage.
