Running terrible after Battery relocation!?

[EclipticalGS]

Well, my cars been acting strange lately and ive been really getting on edge about this thing.

Randomly my car started sucking at dle. 500-600 rpm idle
Runs at about 10-11.7 afr at idle
My throttle when i let off the gas in 5th gear sticks because instead of my wideband going very lean and the injectors shutting off, it instead shows 10.0 afr while im off the throttle??!?
Gas mileage is so bad
When my blinkers go on, my CEL dims on every off rythm of the blinker
Also when my blinker is on, my fuel pump whine changes tone every time the turn signal blinks.
Lights dim when blinkers on, etc.

For my battery relocation I ended up just extendiing the positive terminal wires (in the bay) Via Dist. block to the trunk with 4GA wire. Using the same Chassis to Engine ground. Then the battery is in the trunk with a 4GA wire running to the trunk metal. (shaved the paint and corrosion for best ground).

I am afraid that maybe I need more grounds?? Ive heard of cars running like crap with Janky relocations, If anyone can give me some good advice that would be great.

Also, what can I do to the two 8GA white wires coming from the Fuse box??
Can I replace those with my own 6GA wires?? and also replace the wires that go from the Alt. to the fuse box with 6GA wire?? Any bad effects? Thanks

Im sure its a power issue, because I realised the other day all of these problems were happening after my relocation.

Thanks!

EDIT: CEL is on for Fuel Pressure Solenoid. Its plugged in to the connector but the vacuum lines are ripped out.

I'm guessing you have a bad ground. I too have my battery in the trunk and i had a bad ground when i first moved it. Car would idle and die. So check your ground make sure its solid. and as for replacing the wires i really don't know what white wires your talking about but ya i dont see how replacing 8AWG wires with 6AWG wires would be a problem...

do u have hard long weak starts.

not yet...my starts are normal for any car with all of the EVAP shit ripped out.

my idle is so bad though, and im running at like 10-11 afr at idle and 12.4 cruising. ARGGHH

Not to mention when i rev my car or push the clutch in to stop at a light, my tach needle comes down and swoops 100 rpms.....My bov is recircd and I have 0 boost leaks. hm
