i have a 02 wrx and i installed a boost gauge today. i have it tapped off the bov line. started up fine. let it sit for a minute. revved it a few times and i bogged once then fine. so i took it for a drive. when i ran the pedal hard the gauge only read 5-6 lbs of boost. i pulled over checked the lines. appears all secure. ran it back home and still same thing. took off good but only read max of 6 lbs of boost. tomorrow i am going to cut off the zip ties securing the T fitting and use regular metal clamps
any ideas why its doing this? i will baby it to work and back tomorrow just for safety sake. i didnt hear any vac leak or anything
i have a second issue. i tapped off the harness for the clock. my clock was broke so i just used the power for the boost gauge. now i have no interior lights, or instrument lighting. how do i need to hook up the boost gauge and correctly wire that plug so i have everything that works.
