Lean condition bank 1 & bank 2

Lean condition bank 1 & bank 2
I took my car back to the shop after the PO153 code came up. They replaced the O2 sensor, and also did a computer scan before doing that. They told me there were two other codes stored in the computer. He didn't remember the actual codes, but said it was "Lean condition bank 1 & lean condition bank 2".
So what does that mean? Is that a tuning issue? If I buy a Diablosport or SCTX3 will I be able to fix the issue? What's my best route on this?
I'm curious if me running lean was why my times were so off in the 1/8.

Was the check engine light on the first time? Is it on after the repair? If the the computer still has codes after the repair and the computer was cleared the first time you will have to repair that problem. A tuner will not fix that.

The CEL or SES wasn't on when I bought the car, and never came on until my LT's were installed the other day. The code was P0153 (O2 circuit slow response bank 2 sensor 1) and BBK said to have the O2 sensor changed. So I had them put in a new O2 sensor in (even though they claim all of my sensors were brand new, because they put all new sensors in when installing my LT's.....insurace paid which is why I didn't know).
He said he ran a scan of the computer and found there were other codes stored which both were for "lean condition", 1 code was for bank 1, the other code was for bank 2.
The CEL has not come back on yet, but I haven't driven it much yet since getting it back today.
So I guess my question is what is a "lean condition bank 1 / bank 2" ?
Is that something that is tuning related? and if so which tuners are able to modify A/F from the programmer itself?

Before you go and buy anything else go and get those leaks taken care of. That's what creating those codes in my opinion. I used to get the same codes before I got my leaks fixed.

How can they find the leaks? The shop that had my car was supposed to fix anything with the exhaust system because it was damaged by a different shop, and was supposed to be fully paid for.
They said whomever did my old setup, used the wrong sized flange to connect the Borla cat back to the BBK catted X. It sounded pretty good, but the tick was pretty bad.
I then had the BBK LT's installed, replaced the catted x with a catted H, and they supposedly used the correct sized flange to fix that leak (which I do believe because the car used to sound awesome and loud before they fixed it, now after installing LT's with a catted H & fixing the flange you can barely hear the exaust with my vert top down unless I'm accelerating.) Point is the tick is now much quieter now.
How do you check for an exhaust leak and is it expensive?

Normally I check by parking close to a wall and hitting the gas quickly. If you have a leak you will probably hear a funny sound when the idle is dropping. Sounds may vary but kinda like a rapid fire squeaky sound or something of the sort.
