L67 swap
been a couple weeks all been good but i got a P481 code any common probs and solutions? any help would be apreciated i also need to know if my original 3400 series fuel pump will work with the L67 i notice the car is fine but would it run better with a walbro 255?

you can check the fans by hand with the car off and key off, just spin them by hand and listen for roughness and make sure they both spin freely, if both spin free you should check your fan circuit 2 fuse, its in the lower fuse block under the hood.

no problem
and fuel pump wise, i wouldn't worry too much about it, a walbro is never a bad idea though.
i'm more biased toward aeromotive myself but walbro's are everywhere and work very well

it's just a safety thing, i just got a stock pump for an 05 S/C SS and dropped it in, performance won't increase unless you're running lean right now which would throw a code

Your stock pump SHOULD be enough, but when you start commanding more and more fuel, you will need to upgrade.
I have a Walbro with less than 1000 miles on it if you're interested just PM me.
