I just installed the Mac cai and flashed the computor with the 91 octane tune with the predator now my engine light keeps going on and the trouble code states to lean bank 1 & 2. Do you need to get a special tune for each different cai kit, I was under the impression when you installed a cai you only had to reflash with the tuner and everything would work okay. If so, should I have told Diabalo which cai system I was going to install and they would have sent me one for the Mac, I'm confused, and don't know what to do to get the light off, the car runs really strong.

 

I ordered the C&L CAI + Pred, and the RPMOutlet website said I'll need to download a specific Predator tune for the C&L CAI. Might be the same for your MAC.
