Question on lean condition

[pete57]

I did the 5.3 swap in my 64 last summer and it turned out good. It starts fine idles fine runs great but I keep getting the lean condition codes on both banks. It does buck and fart some when I really get in it. My question is will it be ok to keep driving it while im trying to figure it out? I don't want to maybe do any damage, but I love driving it and don't want to have to park it till I fix it. Been trying to find a tuner in my area but have came up with nobody so far. Thanks
