So i finally pulled my 2.95 pulley off (made a max of 12.5psi... 11psi where i usually shift) and put my new 2.75 pulley on. I went out and made some test runs and it still only made just over 11psi @ 5800
I know it wasnt slipping, as it held boost strong and never dropped off... so i dunno what to think. It seemed as if the boost came in a little quicker. Im gonna pull a plug and see if its running too rich or not (peak fuel pressure was 53psi). Only other thing i can tell might have lost a pound or two was the IAT sensor started coming out, and the line for digital boost guage popped off.
