1996 Mustnag GT-Check Engine light is on

Hi, I have a Jap spec 4.6GT 2v, recently fitted a Magnaflow catted Tru-flow X-Pipe, to match up to the Magnaflow system already fitted, I also have a Bomz CAI, Now the check engine light is on, I had a diagnostic reading done, It had 1 code indicating It is running a bit lean, I was advised to Buy a tune for it or replace injectors for bigger ones, the original front pipes had 6 cats with 2 O2 sensors at the front by the headers & 2 cat heater probes in the first cats, Can anyone help with this problem?

You don't need a tune or bigger injectors to fix that code. If it's a too lean code, you either have a vacuum leak, a bad O2 sensor, or the MAF sensor is dirty, more than likely. There was a guy here recently that had that code, and some injectors were clogged up as well.
