08 foose boost guage question
 

hi guys, i just installed an autometer boost guage in my 08 foose and dont think i did it right ( lol) it shows the truck is making about 20 inches of vacuum while cruising, when i nail it the boost guage goes to the zero. even at 5000 rpm.i tee'd in to the canister on the drivers side of the supercharger ( i will try to post some pics asap ) im thinking i put it in the wrong place is all. can anyone post a pic of your guage install ? thanks https://www.ford-trucks.com/user_gal...id=241865&.jpg
