Quoting 89Patches:
So basically it will only make this "clicking" noise when I am in boost. Sounds like it's coming from the center of the dash board. Car still runs fine drives normally just really annoying. I am guessing a fuel relay?
Any help would be appreciated! Before I start really digging into it.
My old GVR4 used to make a click noice once I went into boost. I used to think it was from behind the dash but it ended up being the ECU. I figured it out because eventually it would click then the car would lose all power. I took the ecu out and swapped it with a friends to test it and it didnt happen so I got mine rebuilt by an old DSM nerd who used to fiddle with Mitsubishi ECU's back in the 80's and 90's. I think my issue was a rare one, but just something to think about.
