so just a few questions. i have the GM stage 3 on my 06 SS/SC

do i need to do anything with the fuel system to lessen my chances of going lean? like the ZZP fuel pump rewire and the Boost Reference fuel pressure system? what does the boost reference do anyway?

also with the ZZP 3" CAI do i need to do something with the MAF(??) because once in a while a bank 1 lean code pops up then goes away..(AFR gauge read ok)..i saw something a while back about a 2 bar system or something like that??

 

you're not going to go lean with gm s3.
the intake is skewing your fuel trims causing the intermittent lean code. nothing you can do unless you want to get a custom tune, or go back to stock intake tube.
