u7194 check engine light w/no cats

[gearheadfx]

I have a u7194 in a 2007 Chevy Surburban 2500 with a 6.0 motor. I put exhaust on the truck and took the cats off and the check engine keeps coming on even with the COT turned off. And I am using the 87 mpg booster tune. Any ideas?

Its the rear O2 codes. No cats will throw it every time.

Does it effect the trucks tune at all? And is there anyway to keep the light off?

[mikel]

need a custom tune to disable the codes to keep the light off.

Thanks

yeah, need a custom tune done in order to get the trouble codes and related items disabled... hit me up if interested... I can do just the trouble code stuff for $35... or a full tune for only $135 - you'll gain even better/quicker throttle response & acceleration, stronger/harder pull, smoother & quicker power delivery throughout the rpms, etc... and sometimes, maybe even a little better gas mileage - if you can keep your foot out of it! haha...
