when i installed the comp, i first left the stock boost elbow on and was getting around 26 psi boost. i installed the elbow that came with the comp, and now all i get is about 13, or so says the guage. the comp elbow simply has a smaller orfice, so am i really only getting 13psi, or is it just causing a inaccurate reading on the guage. should i go back to the stock elbow? i didn't seem to notice any power difference between the two, and the turbo seems to spool equally with either elbow.
