i rebuilt my motor and added the 16g turbo. full exhaust and walboro 255 fuel pump with 650cc fuel injectors.
i started it up 3 weeks ago and it was working okay. except it needs a tune. but up until last week more and more problems occur. the car like to die when i press clutch petal in and it makes a clicking sound when i press clutch in, turn on air/heat ( not A/C). none of my gauges are reading correctly. ive been trying to find out what the cause is and i come up with nothing. any ideas?
 
My car doesnt have any of theses issues but it definitely has some weird ones. Check your wiring/grounds, also check all of your fuses/relays. Use a test light because they can blow without being broken. Also you could pull the ecu and check for anything out of the ordinary, these are all ideas people have gave me. Im no genious but its prob something little, I still havent found out my electrical issues.

Do you have any way to tune the injector flow? You are probably running extremely rich.
 
Are you running a gm Maf or speed density? If not, that blow off valve of your shouldn't be vented to atmosphere. Also, like somewhat mentioned above, you do have an adjustable fuel pressure regulator, right?
 
ok i hooked up a wide band 02 today and it is running extremly rich. and no way to adjust it.

i have the stock maf. and the bov i have is greddy atmosphere type rs. do u think the stock maf might be bad? if so how do u check to see if it is?
 
Your running way to rich without a tune with the 255 and those 650's. You need either an AFPR or DSM Link
