Car pissing me off...running way too rich.

[empera]

ok so we just installed the walbro fuel pump (and clutch). Car didnt want to idle at first and then we lowered the fuel pressure to 15-20psi, idles at ~11.- a/r.
its about the best i can get it to. Heres the wierd part, if i turn on the headlights the a/r's go a bit leaner. Also if i give it some gas it chugs and seems like its drowning or if i give it more gas it'll go lean. I'm getting sick of this car. Anyone have any clue what could be going on here?

what r your mods?

mine did the same.

Is your J-tube still there?

Also that psi is wayyy to low. I bumped mine to 25psi and took out 35% with the maft at idle and 25% with the safc across the map....i idle around low 14 now

Mods are:
VPC, safc2, afpr, walbro, 550's, aem wb, etc...etc...

car was running way rich at idle...i even took out 50% fuel and still nothing until i lowered fuel pressure that much.

Also car started to kinda boggle at idle, rpms going up and down, until i leaned it out a bit, taking fuel out.

Sounds kinda like the fuel pump isn't getting correct voltage.... I get this reasoning from the headlight deal you're having.

...dont understand how that could be...im confused, this car is pissing me off...

Hmmm. can only throw a few recommendations at ya:

1. (are your S-AFC settings correct). # of cylinders, Karman setting, etc?
1a. Go to your setting menu on your TSRM, and make sure u see .5 volts in the TPS section with ign. on and gas pedal untouched.
2. Have you ckd. timing per TSRM?
3. Did u perform the 12v mod?
4. Any codes?
5. Are you VPC knobs pointing at 12 o clock? (u can tweak later if necessary - I didn't have to).

I hope some of the above statements help in solving your issue. Please keep us posted. Thanks and good luck!
