I spliced into the MAP line for my boost gauge. Also to check your gauge you could take an air hose and turn the air pressure down and then blow some air into your boost line to see if it moves the gauge.
yeah defnitely splice into the MAP sensor line, and mine wasn't working for a while either until I found a kink in the line going to the boost guage, so I would splice into that and check the hose for any kinks
Ok call me stupid . lol But where exactly is the line I need to splice into at? draw me a picture. lol There is a line that I wanted to splice into but I will need more hose to get to it, And keep the line safe. Any help would be greatly appreciated. Thanks giuys
Its a smaller silicone hose that runs from just under the turbo to the map sensor mounted on the passenger side of the firewall. Its a small diameter hose that kind of stands alone. Ill see if I can find a photo, I only knew which one it was becuase my gauge came with a picture illustrating where the map sensor line was
