when my bro put on his LTs he eliminated his two back o2 sensors with some connector that went from the front ones to the back ones i think, but i'm not completely sure. maybe some one can shed some more light on this

you can do either
some places will only charge you $25 or so to tune JUST the sensors out.
but if you're gonna do full exhaust, getting a full dyno or street tune will optimize your power and allow changing of things like fan settings, shift points, torque management, skip shift, EGR, AIR....etc...
and cutting the wires off is the same as just disconnecting the sensors...you'll still get the code.
but the code has NOTHING to do with the operating condition of the car/computer.

Predators and handhelds are a total waste of $$ IMO. They are very limited in what they can actually do. Spend a little more for a dyno tune or find somebody close with HP tuners/EFI Live and get a street tune. It is usually a lot cheaper to get a DT "touched up" (by same tuner) when you add more mods too
